NEARBYINT(3) NEWLIB NEARBYINT(3)NAME
1.43 `nearbyint', `nearbyintf'-round to integer
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 (sup‐
posedly) 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
