NAME
fmod, fmodf, fmodl -- floating-point remainder function
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() function computes the floating-point remainder of x/ y.
RETURN VALUES
The fmod(), fmodf(), and fmodl() 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 implementa- tion-defined.

STANDARDS
The fmod() function conforms to ANSI X3.159-1989 (``ANSI C89''). NetBSD 9.2 November 12, 2013 NetBSD 9.2
