positive

So I thought that negative numbers, when mod'ed should be put into positive space... I cant get this to happen in objective-c

I expect this:

-1 % 3 = 2
 0 % 3 = 0
 1 % 3 = 1
 2 % 3 = 2

But get this

-1 % 3 = -1
 0 % 3 = 0
 1 % 3 = 1
 2 % 3 = 2

Why is this and is there a workaround?

I need to determine the amount left of a time cycle. To do that in C I would use fmod. But in ada I can find no reference to a similar function.

I have minimize cost of calculating modulus in C. say I have a number x and n is the number which will divide x when n == 65536 (which happens to be 2^16): mod = x % n (11 assembly instructions as produced by GCC) or mod = x & 0xffff which is equal to mod = x & 65535 (4 assembly instructions) so… >>> More
