NAME
     round, roundf, roundl - round to nearest  integer  value  in
     floating-point format

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

     double round(double x);


     float roundf(float x);


     long double roundl(long double x);


DESCRIPTION
     These functions round their argument to the nearest  integer
     value  in floating-point format, rounding halfway cases away
     from 0, regardless of the current rounding direction.

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


     If x is NaN, a NaN is returned.


     If x is +_0 or +_ Inf, x is returned.
