[@anonymouscoder3557]

pls can u upload a video how to convert a fraction number like 0.28125 into binary using casio calculator if it is possible Thanks Regards

[@sujoy70]

One correction,2's Complement conversion rule is- Scan the number from right to left,keep the bits unchanged,until you encounter 1. Once you've encountered 1,keep it intact and revert all bits after it,i.e if it's 1,change to 0,and vice-versa.

julie an Dinsay I'm the owner and creator of this video and I accept your thanks! :-) You can check my other calculaotr tutorial videos here- goo.gl/uiTDQS

[@sujoy70]

By improper integrals,I think u want to mean indefinite integral,i.e integrals without upper & lower limits. If so,the answer is no. You can only solve integrals with numeric upper & lower values on this calculator using Simpsons 1/3 or Trapezoidal rule

In the beginning of the tutorial,I told that fractional calculations or decimal point(.) is not allowed in Base-N mode. And remember,a binary fractional number is also consists of only 1 & 0. So,11.12 is not a valid binary number,it's a valid decimal fractional number indeed!

[@ahmedelshawadfy3287]

thank you very much it's very helpful video ^_^

[@soumybrata]

thnx for the upload bro, but I cant find the lst video that u r referring here, I mean the one in which u r saying that u mentioned about the 7 golden rules for number system. please give me the link. U r doing a grt job

I was wondering if you could do a video about converting fractions to binary, that would be a lot helpful to me.

[@sujoy70]

+Budd0801 Fractions not allowed in BASE-N mode but you can do it manually. Watch my vid- kzbin.info/www/bejne/aYC1e5SVfdpjiac

[@Abbey3561]

Yeah yeah I meant the manual one! Thanks Sujoy!

[@Digiphex]

Sharp calculators do it simpler and are also very economical.

[@tlgkizilirmak]

Thanks Man

[@Hellothere27816]

These are the standard base conversions. What if I want to do the conversions in random bases such as base 7 or base 9 instead of standard bases (base 10 - decimal, base 16 - hexadecimal or base 2 - binary). Do calculators support that as well?

how does one calculate binary numbers with precision e.g 1001.11+11.12=? using this calculator

[@blurberryism]

Hi thanks for showing this clear tutorial. However, i couldn't convert bigger hexadecimals like A1CF to decimal. using the method shown, my calculator shows syntax error. btw im using fx-991ES plus.

[@blurberryism]

I found what i want thanks!

[@sujoy70]

Thanks

[@kleffordalicayos5073]

sir thank you very much you saved my neck. is there a way to convert decimal fraction to binary using scientific calculator.. ty in advance..

[@sujoy70]

+Portgas d. Ace Sorry but fraction base conversion not possible on calc.

How to calculate Base4 ?

[@shantanusatpute5428]

How do I convert floating numbers? Like if I want 2.34 in binary?

[@sujoy70]

Shantanu Satpute You can't convert fractions/floating point numbers on this calc. However you can easily convert between any base manually. To know the tricks,watch my this video- kzbin.info/www/bejne/aYC1e5SVfdpjiac

Thank you!

[@toocool7350]

Hi Sujoy Krishna, i am using casio FX 991 ES like you. do you know how to make thousand separator? so if i put 1000 it will change to 1.000 or 1,000. i have trouble if put number in million , my eye get confused.

[@sujoy70]

Digit separator is there in 991EX. Check my video- kzbin.info/www/bejne/p6fUpaCQlK1oZsk and kzbin.info/www/bejne/pZndgZ2VeLeKYw

[@sujoy70]

Thanks! Plz subscribe and visit again!

[@LandonTang]

Hi does it apply for Fx- 991ES PLUS? [The 7 Exclusive cool features] Did not mention about digit separator. Please assist. Thanks

[@bhavanikmd7327]

can we do improper integrals using CALCI????

[@tomicemcgrath]

You dont have to press shift to view the different bases

[@Dayum62499]

Are you chattur from 3 idiots? Jk, great video bro. Keep making great content :D

[@rahulsatyanarayana]

how to put point between numbers

[@Utghhiiiujyhftjhhyyhhyjkyghy]

please can you explain how to find (5,9)-9*(4,7)=?

[@sujoy70]

Is that comma in between 5 & 9 and 4 & 7 ? What's meant by 5,9 or 4,7 ?

[@Utghhiiiujyhftjhhyyhhyjkyghy]

yes it is comma::(5-9*4),(9-9*7)

[@sujoy70]

What's meant by (5,9) and (4,7)?

[@Utghhiiiujyhftjhhyyhhyjkyghy]

you know simplex method in operations research? i awnt to know is it possible to solve a row of simplex table in a calci?

[@Utghhiiiujyhftjhhyyhhyjkyghy]

thank you for your concern

I've already shown that in this video! Please watch the video at time 2:30 minutes. And please subscribe to my KZbin channel to get my new videos regularly free of cost!

[@HILLSANGEL6]

dude thank you can you please tell me if i can subtract or multiplay binary numbers using casio ? i have an exam T_T

[@sujoy70]

Yes you can. Not only Binary,but also Hexadecimal,Octal & Decimal. Please re-watch the video carefully,specially the portion between minutes 2:41-3:10. Thanks! And don't forget to subscribe :-)

[@nadaelmokretar1880]

I can't enter letters in hexadecimal code what should i do

[@sujoy70]

Follow the process shown in video, to get alphabets like A,B,C.. press ALPHA key followed by respective letter key. Hope it helps

[@vactum0]

we can do the same without pressing shift key because calculator knows that we are in base n mode

[@lokeshsuthar1737]

and can you please tell me the way for conversion of fractional nos in decimal to binary. btw thanx.

[@stylishkuri3021]

Lokesh Suthar fractions can't be solved on calculators
