RINT(3) FreeBSD Library Functions Manual RINT(3)
NAME
nearbyint, nearbyintf, nearbyintl, rint, rintf, rintl - round to integral
value in floating-point format
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
nearbyint(double x);
float
nearbyintf(float x);
long double
nearbyintl(long double x);
double
rint(double x);
float
rintf(float x);
long double
rintl(long double x);
DESCRIPTION
The rint(), rintf(), and rintl() functions return the integral value
nearest to x according to the prevailing rounding mode. These functions
raise an inexact exception when the original argument is not an exact
integer.
The nearbyint(), nearbyintf(), and nearbyintl() functions perform the
same operation, except that they do not raise an inexact exception.
