I tried googling to get more information about comparison operators in Perl when incompatible data types were involved but wasn't lucky.
I am basically a Java programmer but have been looking at Perl code of late, at work. While debugging a Perl module, I stumbled upon the following code block. I understand Perl has distinct comparison operators for numeric and string data types. But, I am not sure how this works.
Expand|Select|Wrap|Line Numbers
- use constant UNSUBSCRIBE => 0;
- my ($value) = 'n';
- if ($value == UNSUBSCRIBE) {
- print 'n equals 0';
- }
I am not sure how a character ('n') be equal to a numeric number (0). Even the ASCII character value of character ('n') is not 0. Can some Perl guru help me understand what is going on?
Thanks,
