Subject: [Israel.pm] Strange "Argument isn't numeric" warning
Can anyone explain the following phenomenon, or is it a bug in perl?
The code:
use warnings;
print 5 + 7, "\n";
print "5" + 7, "\n";
print "5&6" + 7, "\n";
The output:
Argument "5&6" isn't numeric in addition (+) at - line 5.
12
12
12
So is "5&6" numeric or not? The warning says it isn't, but the
addition evaluates to 12! Shouldn't non-numeric strings evaluate to
zero?
Jason
