in reply to confused: string and number comparison

I think that Perl is taking the string "abcd" and attempting to convert it to a number as you are doing a numerical comparison. Strings that do not start with a digit are numified to 0 (zero) as far as I am aware. Therefore 0 == 0 is true.

Cheers,

    Numbers can start with "." and "-" too. 

    >perl -wE"say 0+'.4'"
0.4

>perl -wE"say 0+'-6'"
-6
