use printf() or sprintf()

perldoc -f sprintf will give you all the details on it but here's kind of how it would be used:

my $number = 29.2;
$number = sprintf("%.0f",$number);

$number should now be '29', the first argument to sprintf (and to printf) is the format string. '%' is where you are going to insert the value, the .0f means, floating point with no decemal places.
