-<<remainder>>, <<remainderf>>---round and remainder
-INDEX
- remainder
-INDEX
- remainderf
-
-ANSI_SYNOPSIS
- #include <math.h>
- double remainder(double <[x]>, double <[y]>);
- float remainderf(float <[x]>, float <[y]>);
-
-TRAD_SYNOPSIS
- #include <math.h>
- double remainder(<[x]>,<[y]>)
- double <[x]>, <[y]>;
- float remainderf(<[x]>,<[y]>)
- float <[x]>, <[y]>;
-
-DESCRIPTION
-<<remainder>> and <<remainderf>> find the remainder of
-<[x]>/<[y]>; this value is in the range -<[y]>/2 .. +<[y]>/2.
-
-RETURNS
-<<remainder>> returns the integer result as a double.
-
-PORTABILITY
-<<remainder>> is a System V release 4.
-<<remainderf>> is an extension.

-/* remainder(x,p)
- * Return :
- * returns x REM p = x - [x/p]*p as if in infinite
- * precise arithmetic, where [x/p] is the (infinite bit)
- * integer nearest x/p (in half way case choose the even one).
- * Method :
- * Based on fmod() return x-[x/p]chopped*p exactlp.
