+FUNCTION
+<<nearbyint>>, <<nearbyintf>>--round to integer
+INDEX
+	nearbyint
+INDEX
+	nearbyintf
+
+ANSI_SYNOPSIS
+	#include <math.h>
+	double nearbyint(double <[x]>);
+	float nearbyintf(float <[x]>);
+
+DESCRIPTION
+The <<nearbyint>> functions round their argument to an integer value in
+floating-point format, using the current rounding direction and
+(supposedly) without raising the "inexact" floating-point exception.
+See the <<rint>> functions for the same function with the "inexact"
+floating-point exception being raised when appropriate.
+
+BUGS
+Newlib does not support the floating-point exception model, so that
+the floating-point exception control is not present and thereby what may
+be seen will be compiler and hardware dependent in this regard.
+The Newlib <<nearbyint>> functions are identical to the <<rint>>
+functions with respect to the floating-point exception behavior, and
+will cause the "inexact" exception to be raised for most targets.
+
+RETURNS
+<[x]> rounded to an integral value, using the current rounding direction.
+
+PORTABILITY
+ANSI C, POSIX
