-// __ieee754_remainder(x,y)
-// Return :
-//      returns  x REM y  =  x - [x/y]*y  as if in infinite
-//      precision arithmetic, where [x/y] is the (infinite bit)
-//      integer nearest x/y (in half way cases, choose the even one).
-// Method :
-//      Based on Mod() returning  x - [x/y]chopped * y  exactly.
-
-// Remainder returns the IEEE 754 floating-point remainder of x/y.
-//
-// Special cases are:
-//	Remainder(±Inf, y) = NaN
-//	Remainder(NaN, y) = NaN
-//	Remainder(x, 0) = NaN
-//	Remainder(x, ±Inf) = x
-//	Remainder(x, NaN) = NaN
