Code:
#! /usr/bin/perl -w
use strict;

my @x = (2.99996,2.17890,3.00002,-2.3456,-2.7890);

($_ > 0) ? ($_ - int($_) < 0.5) ? print int($_), "\n" : print int($_)+1, "\n" : ($_ - int($_) > -0.5) ? print int($_), "\n" : print int($_)-1, "\n" for (@x);

#Un-comment the below two lines and comment the above line if you want output as comma separated values
#($_ > 0) ? ($_ - int($_) < 0.5) ? push (@y, int($_)) : push (@y, int($_)+1) : ($_ - int($_) > -0.5) ? push (@y, int($_)) : push (@y, int($_)-1) for (@x);
#print join (",", @y);
