Re: Re: mod function

Don't forget...

unless ($y % 3) { }

I think that, for the most part, I prefer the explicitness of if ($y % 3 == 0) { } though.

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]
