NAME fmod, fmodf, fmodl - floating-point remainder function

SYNOPSIS #include <math.h>

double fmod(double x, double y); float fmodf(float x, float y); long double fmodl(long double x, long double y);

Link with -lm.

DESCRIPTION The fmod() function computes the remainder of dividing x by y. The return value is x - n * y, where n is the quotient of x / y, rounded towards zero to an integer.

RETURN VALUE The fmod() function returns the remainder, unless y is zero, when the function fails and errno is set.

ERRORS EDOM The denominator y is zero.

CONFORMING TO SVr4, 4.3BSD, C89. The float and long double variants are C99 require- ments.
