       remainder, remainderf, remainderl - remainder function

       #include <math.h>

       double remainder(double x, double y);
       float remainderf(float x, float y);
       long double remainderl(long double x, long double y);

       These functions shall return the floating-point remainder r= x- ny when y is non-zero. The
       value n is the integral value nearest the exact value x/ y.  When |n-x/y|=0.5, the value n
       is chosen to be even.

       The behavior of remainder() shall be independent of the rounding mode.

       Upon  successful  completion, these functions shall return the floating-point remainder r=
       x- ny when y is non-zero.

       If x or y is NaN, a NaN shall be returned.

       If x is infinite or y is 0 and the other is non-NaN,  a	domain	error  shall  occur,  and
       either a NaN (if supported), or an implementation-defined value shall be returned.

       These functions shall fail if:

       Domain Error
	      The  x  argument	is +-Inf, or the y argument is +-0 and the other argument is non-

       If the integer expression (math_errhandling & MATH_ERRNO) is non-zero, then errno shall be
       set  to [EDOM]. If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero,
       then the invalid floating-point exception shall be raised.

       The following sections are informative.


       On  error,  the	expressions  (math_errhandling	&  MATH_ERRNO)	and  (math_errhandling	&
       MATH_ERREXCEPT) are independent of each other, but at least one of them must be non-zero.
