Signed Binary (Sign and Magnitude & Two's Complement)

[@hazimakmal5899]

There's another shortcut I've learnt at school for Two's Complement. The left most bit of a byte represents -128 while the other bits represent their normal corresponding denary digit. So from the left, a byte would be -128 64 32 16 8 4 2 1 An example is --35 (like in the video): -128 64 32 16 8 4 2 1 1 1 0 1 1 1 0 1 11011101 is the correct Two's Complement as shown in the video. I hope you found this useful.

Thank you so much for making these. My computer teacher quit halfway through the semester so we couldn't complete the course. Soo thankful to you.

This method is confusing, at school we did a different method which is easier. You first find if the number is positive or negative. If negative you place a one at 128 then you subtract from 128 until you reach the number

[@hero_bsb6314]

that method is confusing

[@mikeywalsh3983]

we learnt that way too at school, its way easier

Hi, can you do a video on fixed point and floating point conversion ?

This is absolutely useful thank you so much

THIS IS EPIC

[@rishabhkalia1282]

What about a 3 digit number in negative form how will you do that?

[@siby18]

Thanks, very useful!

[@schalkdb4533]

hi just a quick question, when converting from a negative number in two's compliment to denary and the last number happens to be zero, when i subtract one what will the outcome be

[@hadyhed5426]

you cannot actually do that as 1 can never be subtracted from 0
