twos-complement

I've decided to do it this way

flip numbers 0=1, 1=0
add 1 to LSB
if carry, loop until array[i]==0

But I'm stuck on the last point; how can I say that in a conditional loop?

Hi every one. I am new programmer in Obj-C and cocoa. Im a trying to write a framework which will be used to read a binary files (Flexible Image Transport System or FITS binary files, usually used by astronomers). The binary data, that I am interested to extract, can have various formats and I get… >>> More

We have 2's complement for integers that allows us to perform operations without worrying about the sign. That is a big help at the implementation level. Similarly we have so many floating point operations and yet we rely on sign and magnitude. What is the reason? Why can't a 2's complement like… >>> More

I have a control that has a byte array in it. Every now and then there are two bytes that tell me some info about number of future items in the array. So as an example I could have: ... ... Item [4] = 7 Item [5] = 0 ... ... The value of this is clearly 7. But what about this? ... ... Item… >>> More
