Re: Interpreting values alternately as $trings and Integers = confused response by Perl

If you write "$ary[0] = '12'", you assign the value "'12'" to $ary[0]. Perhaps you were thinking of "$ary[0] == '12'"?

(elbie): Interpreting values alternately as $trings and Integers = confused response by Perl by elbie (Curate) on Apr 14, 2002 at 20:07 UTC
Note that perl has two different kinds of comparison operators, one for strings (`eq`) and one for numerical values (`==`) Minor point, but you should probably use `$arr[0] == 12` to get a true numerical comparison. i.e. Drop the quotes. elbieelbieelbie	[reply] [d/l]

I agree that the quotes should probably be removed, but for reasons of clarity -- that is, people are likely to glance at the code and accidentally interpret the == as an eq due to seeing quotes. == does "true numerical comparison" whether or not there are quotes there; the string gets converted to a number for the ==, and it DWYM.
