Re^2: How can I test for the representation of an integer?

Trouble with that is it treats both 1, and '1' (and 1.0 and '1.0') as looking like numbers (albeit with strangely different values of true)

use Scalar::Util qw(looks_like_number);;

[0] Perl> print looks_like_number( $_ ) for 1, '1', 1.0, '1.0', '1o';;

But the OP wants to distinguish between 1 stored internally as an integer; and '1' stored internally as a string.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice.
