NAME
       nearbyint, nearbyintf, nearbyintl - floating-point rounding functions

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       double nearbyint(double x);

       float nearbyintf(float x);

       long double nearbyintl(long double x);

DESCRIPTION
       These functions round their argument to an integer value in floating-point format, using the current rounding direction and without raising
       the inexact floating-point exception.

RETURN VALUES
       Upon successful completion, these functions return the rounded integer value.

       If x is NaN, a NaN is returned.

       If x is +-0, +-0 is returned.

       If x is +-Inf, x is returned.
