fmod, fmodf -- floating-point remainder functions
Math Library (libm, -lm)
#include <math.h>
double
fmod(double x, double y);
float
fmodf(float x, float y);
The fmod() and the fmodf() functions compute the floating-point remainder
of x/ y.
The fmod() and the 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() and the fmodf() function returns zero
is implementation-defined.

The fmod() function conforms to ISO/IEC 9899:1990 (``ISO C89'').
