Check the Number is floating point number or not

[sivasakthi]

Hi All,

How to check the number is floating point number or not???

I have tried the code following,

#! /usr/bin/perl
use strict;
use warnings;

my $val=124718247874.543;
if ($val =~ m#^(\d+)\.(\d\d\d)#;
{
print "it is a float\n";
}


Thanks,
Siva
