[@dontdishfish5861]

For anybody wanting to know reason behind that number, here it is: 2147483648 + 120 (the number of floors in the regular mine) equals 2³¹. This means that the floor number of the mine and skull cavern is stored using 32 bits in the memory. The 1st bit is probably always 0 as the floor number is never negative (a 1 as tge first bit will always give a negative value in most instances with binary) a so the 1st bit is practically not used and only the next 31 bits are used. The largest number, therefore that the floor number can be is 2³¹. But 120 of the floors belong to the mine so the largest skull cavern floor number is 2³¹ - 120.

Going by the depth of skull cavern, assuming it doesn't teleport you to some weird pocket dimension and assuming each floor is about 10 feet, the planet stardew valley is on is about 500 times the size of planet earth, just going off of this size alone. Since you haven't even hit the mantle yet, it's either even larger, or the composition of their planet is completely different to everything else in existence. The people that live here have to skeletal structure of pure titanium to not be crushed the gravity. Moreover the pressure as well as heat of skull cavern's bottom floor would be so intense it probably should just kill everything, mumps and monsters included. Pam would probably be fine though.

[@SmashEgg11314]

so assuming each floor is about 10 feet high (for simplicity) the entirety of skull cavern is 4,067,203 Miles deep. But the diameter of the earth is only 7,197 Miles, meaning skull cavern has to loop around the entire world multiple times. If we assume it stays just below the surface the entire way we can use the earths circumference of 24,901 Miles to figure out that it loops around the earth a total of 163 times. for further reference, skull cavern is over 300 times longer than the Great Wall of China, it more than qualifies to be a world wonder, and DF just sets off bombs in it.

[@tensorflaw]

or stardew valley takes place on planet that has a diameter of 8m miles, a circumference of 25.5m miles, and a surface area of 708 trillion miles. that's roughly 10 times bigger than the sun. a planet of that size and earth like material would surely collapse on itself into a black hole

The reason for such the high number is that the number 2,147,483,647 is the max you can go before it overflows and jumps to an insanely low negative number. However, you'll notice the number here isn't 2,147,483,647, but rather 2,147,483,527. Well, if you remember what DF said about the 120 floor glitch with the bomb, and how the 121st floor is just the 1st floor of skull cavern, that's exactly it. 2,147,483,527 + 120 = 2,147,483,647, the max limit of the 32 bit integer limit.

@@joshdevio because it's just... easy? considering the way the floors are procedurally generated, it's likely that the level depth is literally just a signed int.

It's really interesting that game creators were prepared for someone reaching the int value in floors.

Without mods it would take 34 years straight at best, meaning that assuming your PC doesn't break it would be a multi-generation feat

If you were to be skipping it one floor at the time, one floor by the second, it might just take double that.

Unfortunately as it's procedurally generated, they weren't prepared for it, it was just the physical limitations the game would allow. Would be very cool if ConcernedApe had prepared for it and put something special on the last floor though!

[@MaxRollison]

I think they didn’t worry about it at first. But patched it later on, just like the dupe glitches. I guess it really is a simple fix though

[@Lauren_C]

Alexander Rollison Theoretically, it isn’t difficult to implement a couple checks before and/or during floor generation. Not sure how the dev implemented it, but one way would be to check the current floor against a preset variable. If the value is equal to or greater than the limit, then you could simply fail to generate a floor. The load times are very speedy, which suggests that the next floor could be generated in advance before you actually do go down, probably before ladders are ever generated. In this case, a failed floor generation can return a value (a boolean perhaps) that can be used to prevent further progression. Shafts would probably require special handlings due to their variability. This video didn’t display the behavior of shafts within reach of the bottom floor, so I can’t say with any certainty how it will handle potential overflow situations. The safest means I know of would probably involving generating the random number (floors to jump down by) in advance, then run a loop in the background to increment the floor value while running the checks against the floor limit. If the limit is hit, then the difference returned will be the amount of floors you skip, preventing further progression.

@DangerouslyFunny I'm pretty sure someone already pointed this out. Stardew Valley is a 32bit game, The number 2,147,483,647 (or hexadecimal 7FFFFFFF) is the maximum positive value for a 32-bit signed binary integer in computing. I added 120 to 2,147,483,527 because the mines do count as the first 120 floors. So basically you reach the end of the possible numbers generated in hex value.

[@lynzylu5]

[@wrenthdavis5174]

It's the limit because the floor number is stored as a 32 bit signed integer. So 31 bits of precision and 1 sign, means 2^31 possible floors. We ignore the fact that it can be negative as this is just the way that the integer is stored. So 2^31 = 2147483648

[@SlickNickP]

Computers use a base 2 number system, i.e. looking at things in the form 2^(x). Our society generally uses a base 10 number system, which is why base 2 numbers might look a little weird to the human eye. You’re used to organizing numbers in terms of 1, 10, 100, 1000, etc. but a computer thinks of things in terms of 1, 2, 4, 8, 16, etc. In this case, 2^(16) = 2,147,483,648. So, ending at 2,147,483,648 is similar to ending at something like 1,000,000,000,000 in the base 10 number system that you’re used to. It just makes sense to end at an even number like that, and makes the most of the memory available. The size of the memory set aside for rooms in this area was probably 2^16 (aka, an integer with a limited memory size of 2^16). In Stardew Valley, the skill cavern number is a little less than 2,147,483,648 but very close. I’m guessing that ~100 extra rooms were set aside for other locations in the desert or something. Either way, seeing something so clearly based on a base 2 number system is typical for anything with computers!

The bottom of skull cavern is the upper limit of an int32 number minus 120 floors for the mines. It would crash if it passed that limit, so most games loop back to the beginning (which is the same limit but negative) or in the case is Stardew Valley it looks like it prevents the number from incrementing

[@MrArrmageddon]

Getting to floor 2,147,483,527 in one lifetime without cheating? Is it possible? Here is a rough math breakdown coming from me. (Not a math buff by any means.) I got some of this info from Wiki. Lets Start with this. "Time is the process in which Stardew Valley proceeds. Each day is 24 hours, and each hour is sixty minutes. Time passes in ten minute intervals. Each interval equates to about seven seconds in real-time. There are 7 days per week. An hour of the game consumes 42 seconds of real-time. From that, we can assume that a full game-day duration is about 17 minutes." So if each day is 17 minutes of real life time. And the record for legit vanilla (No modded help etc.) Skull Mine Depth is 500ish give or take 100 or so? Is that true? I don't know even on a full day and really good luck I have hard time getting to 100. My record is 115 ish. But in the video you said you got to 500! I don't know if you used a little help from like a time slow down mod but you said others have gotten a little further? So I'm going to use 750 floors as a value for the current record for vanilla. I don't know how wrong that is. But I assume it's very difficult to beat that? Heck personally I think it's absolutely impossible but after seeing speeds runs and Good Games Done Quick anything is possible. But it's better to over estimate when it comes to the math I'm about to do. And it's fair to assume that 750 is over estimating. So 750/17 = about 44.117 floors per minute. More Info from Wiki. In Canada, the average life expectancy was 80 years for males and 84 years for females in 2018. So I'm going to pick 85 years as general over estimation. I'm also ignoring work, sleep, eating, bathing all that does not matter. So 85 years of dedicating time traveling downward in Stardew Valley Skull Mine. So that alone is a MASSIVE over calculation. 85 Years = 44,676,000 Minutes 44,676,000 ( 85 Years ) x 44.117 ( Floors Per Minute ) = 197,097,109.2 (Floors Deep) So yeah the average Canadian or let just say person if they started mining downward in Skull Cavern the moment they were born till the there death. On average without sleep, work, eating, or anything else they would be extremely lucky to reach just floor 197,097,109.2 (Target Floor) 2,147,483,527 / (Projected Maximum) 197,097,109.2 = 10.895. So even after all this we are still off by 10.985. So even 10 lifetimes would not be enough. And I'm to lazy to figure out how much time someone has to eat, sleep minimum there whole life and deduct the ages where someone is to young. Like the 1st 4-5 years of there life. The real calculation is at best half of the one I put up. Like any real person trying this would have to eat, sleep etc... So DangerouslyFunny your 100% correct when it comes to billions of pretty much anything it's beyond human life time.

[@needtowin316]

Rough maths...

[@KizzyJay]

I was expecting for the skull cavern to roll over when you tried to go to floor 2,147,483,528. What I mean is that I was thinking you might have ended up on floor 1 of the mines. Though I think the dev's didn't put in a roll over feature for the 32 bit integer limit mostly because it isn't possible to hit that low of a floor without cheating.

[@lnugl]

Concerned Ape used an int primitive data type to store the value of the floors. An int data type can count up to the value of 2,147,483,647 or 2^31 - 1. If you subtract the amount of floors in the regular mines you get 2,147,483,527

[@Eddygeek18]

The dev must of added error checking for the floor switching function, 2.147 billion is the signed 32 bit integer limit, after that it overflows to negative so floor -2.147 billion, it's interesting that the dev likely adding this error check for such an impossible event without mods, but if modding was an early though in development it may have been put in the game for that purpose incase modding allowed playing to get to that floor. Great skill thinking ahead by the dev if the error checking was put in rather than a built in engine feature.

[@CajunCrustacean]

Fun info: if you assume 10 ft per floor (for ease of math), that makes skull cavern roughly 4,067,203 miles deep. Or in other words a bit over 827 times the diameter of the Earth.

[@lgfromie]

If you were to place a crafted staircase down for every floor, with each action of crafting and selecting taking 1 second for one stair case, it would take approximately 2 1/4 days to reach this level. Still, if you are not using a bot or spam clicker, this could make the time to do this approximately 4 1/2 days (taking 2 seconds per stair case) with no other variables. I may have accidentally created a computation error, but this is what I got.

Erm actually no, 64 bit limit is (2^63)-1 which is exponentially higher than this (exactly 2^32^2÷2-1) or a little more than 9.2 quintillion (won't bother typing a 19 digit number) This case, on the other hand, is actually a 32 bit limit which is 2^31-1 which is 2147483647 or the maximum floors

[@joeebiden_]

god i'm having a mental break down but hearing DFs voice instantly made me feel better

[@periwinkle98]

2147483527 is not far off the 32-bit integer overflow value (probably like 100 off or something) so my vaguely educated guess would be that when you consider all of the components that go into each floor, this is the highest number that can be reached without hitting the integer overflow. Concerned Ape probably put something in place to prevent overflow, or maybe the software used to develop the game has built in features that prevent it, but yeah. It's most likely just to prevent overflow, which would break the game and cause all sorts of crazy crap. For those interested, computers don't count up in ones like humans do, they use binary. The integer function in many programming languages is naturally 32-bit, because then it can be run on both 32 and 64-bit computers. Also usually software engineers don't need 64-bits worth (which is like 9 billion or something) of information, whatever it may be (money, health, exp etc.). Often this will be like a max limit for things in games, providing there aren't other limiting factors (like weight loads preventing you from pocketing 2 billion healing potions in Skyrim). I'm a physics student not a computer science student, so if some of this is a little off my apologies. Edit: I hadn't fully watched the video before posting this, but yeah, that -8 floor is what I was talking about, the game code overflowed and ended up back at zero but you obviously can't go to the zeroth floor so the game doesn't know how to deal with it and it breaks.

[@leahgreene5880]

The 64 bit integer limit is way more than 9 billion. A signed 64 bit integer can be up to 2^63 - 1, or 9 quintillion (9.22×10^18).

[@periwinkle98]

@@leahgreene5880 ah alright cool, yeah I knew it was 9 something, but like I said I'm a physicist not a computer scientist, thanks for the fact check

[@catboygamer]

From what I know you are right the difference is not far off the 32 bit integer value. I learned it by watching a video explaining how because of the 32 bit integer that if you go past that many blocks out by getting out of the world border the world itself breaks. Now I didn't compare the difference in floor level by removing bottom most floor number from the 32 bit integer number but I have seen a few people saying the exact difference is 120 I believe. And 120 is how many floors there are in the normal dungeon / the mines which as shown by that old bomb glitch that DF mentioned skull cavern floor one is technically the next floor below the mines floor 120 making skull cavern floor one technically floor 121 which means that the difference if the other comments I saw were correct then basically you do hit the 32 bit integer but it just doesn't look like you do because it calls the first floor of Skull Cavern floor 01 instead of mines floor 121. At least if what I have seen in some other comments is correct.

[@letsb3nameless665]

If I did math right, and you didn't eat, sleep, or do anything else, AND had infinite ladders, and you placed one ladder every 5 seconds, presuming that's how long it takes to place it, scroll to the next ladder, and go to the next floor, it would take approximately 341 years to get to the bottom. So it is possible. If you use a bunch of people constantly swapping around in shifts as they die.

[@nymad7054]

The reason that 2.14 billion floors is the max is because the type of value the floors are stored as is an int and the highest that goes is that number, 2.14 billion is considered int overflow

[@brittany1382]

with a minor tweak to the code, CA could double the depth. 2^32 is the size of an int, yes, but its a SIGNED int meaning it stores both positive and negative values (+2bil and -2bil). If CA switched it to an unsigned int, then it won't register negative values, but it will double the size. if CA mage them long's (64 bit) you're looking at 9/18 Quintillion floors for signed/unsigned

[@the_blueeagle]

Well, this video is kinda old but here an explanation if some one is still interested of wht I think is happening: The data type storing the level of the cavern is called an integer, which can not hold a larger number then 2 147 483 647. If you subtract the 120 levels of the normal mine you get to 2147483527, the last level that the skull cavern can physicly generate. This can actually be seen in a lot of games/programs where there is no need for huge numbers and since 2 billion is more then enough to acount for a normal play through, developers often to choose to use integer instead of other variables to save some space. It is nice to see though, that the game actually "handles" higher numbers with simply not reacting to the input, often this would crash games or cause some weird glitches. Hope that was interesting if someone actually read this xd

[@FoulOne]

The highest 32-bit signed integer is 2,147,483,647, and thus the highest value that can be represented in this game. It is 120 more than the number of Skull Cavern floors because the game uses the same value to assign values to the mine's floors, so dungeon floor 121 is Skull Cavern level 1. Another fun bit, is if you make it to floor 77,256 and go down one level you wind up in the Quarry Mine dungeon, because that uses the value 77,377 to mark it.

[@MarcoSpaceMan276]

I'm also guessing there's some sort of floor or number check when you touch the ladder; the int highest number itself I don't think would stop you from going into the ladder

[@OriginalPiMan]

If you go down 15 floors every second, representing finding a shaft that drops you the maximum amount immediately every time, it is around 4.5 years. Go by ladder instead and it obviously takes 15 times longer, or just shy of 70 years uninterrupted.
