Hi, I'm having trouble trying to figure out a code that converts negative decimal numbers to binary, as well as specifying the number of bits. For example. convert -18 using 8 bits. This should come out as 10010010 doing it manually, I think. I'd appreciate the help, thanks.

Jump to PostWorking with negative numbers in binary you need to use twos complement method. It is a bit confusing to start with (well it was for me). I use it a lot for checksum calculations. Hope this helps.
