NAME
     ffmmoodd - floating-point remainder function

SYNOPSIS
     ##iinncclluuddee <>

     double
     ffmmoodd(double x, double y);

     long double
     ffmmooddll(long double x, long double y);

     float
     ffmmooddff(float x, float y);

DESCRIPTION
     The ffmmoodd() functions compute the floating-point remainder of x/ y.

     Specifically, the 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 magni-
     tude less than the magnitude of y.

SSPPEECCIIAALL VVAALLUUEESS
     ffmmoodd(+-0, y) returns +-0 for y not zero.

     ffmmoodd(x, y) returns a NaN and raises the "invalid" floating-point excep-
     tion for x infinite or y zero.

     ffmmoodd(x, +-infinity) returns x for x not infinite.

STANDARDS     The ffmmoodd() functions conform to ISO/IEC 9899:1999(E).
