[aclug-L] Formatting numbers in Perl!

[Mohammad Islam <sohel@xxxxxxxxxxxxx>]

Hi,

I was wondering someone can provide  some pointers regarding formatting
numbers in perl.

Lets say I have the following variables:

$price = $49.50;
$quantity = 2;

$sub_total = $price * $quantity 

print $subtotal show 99.

Now I want $sub_total to be $99.00 [up to two decimal places].

How can go about accomplishing it? I have looked into printf from the
"Learning Perl" book, but i do not intend to print to the screen. I want
to store the formatted value to another variable for later use.

Any help would be gratly appreciated.

Thanks.

Moe
