I am a little confused about the difference between ceilinged and floored divide/modulus: which handles negative divisors returning negative of absolute remainders and which returns reverse-order positive remainders. I am looking for the latter in a cc65 C program. If I'm not making myself clear, let's say I'm dividing -2 by 3. I want the remainder to 1, not -2. How do I do that? C seems to by default give -2 as the remainder. I also want a vocabulary check as mentioned.
BTW, this is for compression software.
