-/* fmod.c
- *
- * SYNOPSIS
- *
- *    #include <math.h>
- *    double fmod(double x, double y)
- *
- * DESCRIPTION
- *
- *    The fmod function computes the floating-point remainder of x/y.
- *
- * RETURNS
- *
- *    The fmod function returns the value x-i*y, for some integer i
- * such that, if y is nonzero, the result has the same sign as x and
- * magnitude less than the magnitude of y.
- *
- * On a VAX or CCI,
- *
- *    fmod(x,0) traps/faults on floating-point divided-by-zero.
- *
- * On IEEE-754 conforming machines with "isnan()" primitive,
- *
- *    fmod(x,0), fmod(INF,y) are invalid operations and NaN is returned.
- *
