Multiplying variables?

[Hozzer]

This might be a bit of a nube question but here goes.

I have 2 variables I'm multipying
$totalCommission = $numSales * $commissions;

This runs in a foreach loop so let's say I have 2 sales at 9.25 which adds up to $18.50, why is the zero stripped off when I output $totalCommission?

 

[jpadie]

because it is returning a float and it is correctly stating that the result is 18.5.

if you want the output formatted as a decimal number of a certain number of decimal points, use number_format()

Thanks jpadie

Realistically speaking, trailing zeros are utterly useless.

Geates,
While I agree, when displaying prices and such it does look better
