NAME

fmod, fmodf, fmodl -- floating-point remainder functions

LIBRARY

Math Library (libm, -lm)

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);

DESCRIPTION

The fmod(), fmodf(), and fmodl() functions compute the floating-point remainder of x/ y.

RETURN VALUES

If y is non-zero, the fmod(), fmodf(), and fmodl() functions return the value x-i*y, for some integer i, such that the result has the same sign as x and magnitude less than the magnitude of y. If y is zero, a NaN is produced.

STANDARDS

The fmod(), fmodf(), and fmodl() functions conform to ISO/IEC 9899:1999 (``ISO C99''). DragonFly 3.9 June 19, 2008 DragonFly 3.9
