Question

I have this piece of php code:

$skill_amount = round(pow($rarity,1.25));

It should be noted that $rarity is derived from a query.

I am inputting values like 0,2,4,8,16,32,64 into it.

99% of the time it is working but a small amount of times my users are reporting huge values like:

13771, 77936

What could possibly be causing this?

Answer 1

"What could possibly be causing this?"

A large or unexpected value for $rarity.

If you can inspect all possible values of $rarity, you should do that. Otherwise, you could do some basic debugging.

if ($skill_amount > some sane value) {
    // log $skill_amount & $rarity to a file or email
    // maybe also some other investigative values, like stuff that assisted the derivation of $rarity
}
