UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Math in PERL

Is there a way to make to variables, and when they are defined, they can be used in a formula.

EX: I'm running an RPG UBB. I want to take the user's post count and rank (if I make their rank definable in the profile screen via drop-down list) and want to use the formula: (where $HitP is Hit Points (I want to make a variable for that) $Posts is there post count (DUH) and $HitPRank is the value for the rank they chose.

So if my total posts equaled 2 and the rank I chose had a HitPoint value of 3, the formula would be (with the numbers plugged in)My hit points would be 34 (I'd like it to round off, if possible.

Is math like this doable in PERL, and if so, what are the commands. Thanks for listening to my ramble and I hope for good answers.

If over means devided by, then here is your answer:


I believe...probably something wrong -- always is >:0)

Thanks a lot. Can you just give me a list of all the symbols for math functions? I really need these and it would be greatly be appreciated.

He wants rounding, so:

$HitP = sprintf("%.0f", $Posts * 50 / $HitPRank);

parenthesis are not needed on the math since it's just multiplication and division, both which have the same precedence.

This was just a random formula, not the one I was gonna use. I just want the fomula and symbols to use.

Here's documentation of the Perl operators:

I am so MUCH more confused than I was before. Thanks anyway though.

I'm working my way through Programming Perl (having already read Learning Perl and CGI Programming with Perl).

I thought C++ was complicated, but after finishing the chapter on regular expressions, my reaction was Are these guys nuts?

Of course, but I always find it simpler to read when using paren's...
