FMOD(3) BSD Library Functions Manual FMOD(3)
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.
SEE ALSO

STANDARDS
The fmod(), fmodf(), and fmodl() functions conform to ISO/IEC 9899:1999 (``ISO C99'').
