How would you go about determining if a number is an integer or a float?

$number = 1.2334;
if($number =~ /\./)
{
print "This is a floating point number.";
}
else
{
print "This is a integer.";
}

gareth, the only problem with that is that it will fail with a number like 3.0 which you might want interpreted as an integer.

i would suggest using this code

Code:

my $num = 3.1254;
if($num - int($num)) { print "is float"; }
else { print "is integer"; }
