FMOD(3)                FreeBSD 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
     math(3)

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