NAME
fmod - floating-point remainder function

SYNOPSIS
#include <math.h>

double
fmod(double x, double y)

DESCRIPTION
The fmod() function computes the floating-point remainder of x/ y.

RETURN VALUES
The fmod() function returns 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.

SEE ALSO

STANDARDS
The fmod() function conforms to ANSI C3.159-1989 (‘‘ANSI C’’).
