Re: mod function

$y % 3 == 0 && do { }
$y % 3 || do { }
do { } if $y % 3 == 0
do { } unless $y % 3
[download]

Or of course you could just drop the do: and use the code you posted!!!

Don't forget... `unless ($y % 3) { }` [download] I think that, for the most part, I prefer the explicitness of `if ($y % 3 == 0) { }` though. -sauoq "My two cents aren't worth a dime.";	[reply] [d/l] [select]

I'm curious (genuinely curious, not picking a fight) as to why `if (...)` is more explicit than `unless (...)`? Is it because if is more ubiquitous?	[reply] [d/l] [select]

To me the advantage of: `if ($y % 3 == 0) { }` [download] is that you are explicitly stating that you are testing for a modulus being zero. With: `unless ($y % 3) { }` [download] you are saying you are interested in Perl's idea of the statement's truth/falsehood - which is a subtly different concept.	[reply] [d/l] [select]
