Simple Answer

[Ganbree]

In a simple script im dividing to very differant numbers,
problem come from the exponents it can create:

$var1 = $num1 / $num2 * 0.01; // 0.01 is a constant answer = 8.14947503631E-06

if($var1 < 0) {$var1 = 0;}

problem...
$var1 still equals 8.14947503631E-06
is a exponent stored as a string and is being compared to 0,
i couldnt find a is_exp or is_expo / is_exponant etc...

doh didnt put what I wanted to do:

I want the small exponants to be set to 0 and the large exponants set to a 0.025

[kobmat]

from the code of course $var1 will still be 8.14947503631E-06
cause 8.14947503631E-06 is still greater than 0..

You should decide until which value you want the $var1 to be set to zero
say

if($var1 < 0.00001) $var = 0;
