Limiting a variable to only 2 decimals (.XX)??

[suess0r]

If I have a multiplication calculation for a PHP variable, how can I set it to only limit to 2 decimal places (.XX)

 

I'm passing the amount value to a merchant account and it's kicking it back if it's over the 10th decimal spot. Thanks!!

number_format($number, $decimals)

 

Example:

<?php
echo number_format(1.33333333333333333, 2);
//returns 1.33
?>

 

There are more parameters, read the documentation to view what else you can do.
