+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.
