PHP Calc Percentage

[DaemonProjects]

Hello all,

I am trying to make a discount function, but I am not sure how to give the discount.

If I have $250 and I want to give it a 100% discount (should be $0.00) how would I calculate that using 100%?

thanks

$discount = 100;
$price = 250;
$final_price = $price * ( 1 - $discount/100);

% sign itself is a modulus operator.
