fmod, fmodf - floating-point remainder functions
#include <math.h>
double
fmod(double x, double y);
float
fmodf(float x, float y);
The fmod() function computes the floating-point remainder of
x/ y. The
fmodf() function is a single precision version of fmod().
The fmod() and fmodf() functions return the value x-i*y, for
some integer
i such that, if y is non-zero, the result has the same sign
as x and magnitude
less than the magnitude of y. If y is zero, whether
a domain error
occurs or the fmod() function returns zero is implementation-defined.

The fmod() function conforms to ANSI X3.159-1989 (``ANSI
C'').
