Mathematical Library Functions                      nearbyint(3M)



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

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     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.
