Decode a binary, post a binary

Post Reply New Topic

Decode the number above you and state whether it is positive or negative
(if the leftmost bit is 0 it's positive, if 1 it's negative)
Then post your own binary. It can be 8bit, 16bit, 24bit, or 32bit

10101011

On your calculator you can use byte mode for 8bit numbers. It will tell you that a number with a 1 on the far right is negative and a 0 in the far left is positive. Example: 1000 0000 displays as -128

85?

I don't understand the 'positive or negative' bit (no pun intended).

If the bit on the far left is 0, it's positive; if it's 1, it's negative. It's negative 85

Is that your own rule...that you just concocted for this game (which would be ok)?
Or are you claiming that that is how binary works?

No, it's legitimate. It's two's complement binary numbers. DeepHour was correct but it was a negative number. The same works on your calculator in programmer mode

01011001 is 89 in decimal, it's a positive number

What is 10010010 00001100?
