+INDEX
+	fminf
+
+ANSI_SYNOPSIS
+	#include <math.h>
+	double fmin(double <[x]>, double <[y]>);
+	float fminf(float <[x]>, float <[y]>);
+
+DESCRIPTION
+The <<fmin>> functions determine the minimum numeric value of their arguments.
+NaN arguments are treated as missing data:  if one argument is a NaN and the
+other numeric, then the <<fmin>> functions choose the numeric value.
+
+RETURNS
+The <<fmin>> functions return the minimum numeric value of their arguments.
