[SOLVED] Math Issue

[2K]

$f1 = 300;
$y1 = 200;
$yatk = 75;
$fdef = 125;
$y3 = $y * $y2;
$f3 = $f * $f2;

The code functions 100% fine when the numbers entered into the text box (which is where $y and $f come from) are odd. It will work fine if $y is even (20, 22, 24) and $f is the next number (21, 23, 25).

 

If $y = ODD and $f = EVEN it won't work. And if it's 2 even numbers it won't work.

 

 

So, question is: how do I get it to make...

1. 2 even numbers work

2. Odd ($y) and Even ($f) numbers work

[Ken2k7]

It should work regardless, but what's $y2 and $f2?

[2K]

In an error of mine (quickly trying to change the variables into something less...confusing), I seem to have put a 2 where the 1 should be. I know it _should_ work, but something is wrong.

 

New updated code...still same issues...

$f1 = 300;
$y1 = 200;
$yatk = 75;
$fdef = 125;
$y3 = $y * $y1;
$f3 = $f * $f1;

You'll probably have to elaborate on how it doesn't work. You're just multiplying two numbers. I don't see how that can fail unless you enter a huge number so it overflows.

[Maq]

It probably outputs 0 because $y and $f aren't ever initialized, they don't exist!

 

$y3 = $y * $y1;
$f3 = $f * $f1;

Maq, I don't think the OP post all of his code. $y and $f as stated came from some input fields. I assume he used the correct $_GET, $_POST, $_REQUEST or filter_input() to get the information.

Right, my bad, need to get some sleep...

 

So OP, if there are 1 or more even numbers then it won't work...?  Like everyone else said, you may want to post some more code and elaborate on what, "it won't work" means.

After a bit of working on it on my own, I got it working by rewriting the echo statement a tad (that would display the answer).

 

Thanks all who responded...sorry if I wasted anyone's time.

That's good to hear, do you mind sharing the final code?

he's probably worried on some patent leak... LoLxxx
