◆ cmod() [3/3]

int cmod ( int x,
int y )
inline

This is similar to fmod(), but it behaves properly when x is negative: that is, it always returns a value in the range [0, y), assuming y is positive.

This integer-valued function is provided since the built-in modulo operator % does not work properly for negative x.
