    Calculating Prices In CGI/Perl

    Hi,

    I'm trying to calculate prices in CGI/Perl, but I'm having a problem with the loss of trailing zeros. ie.:

    $Price1 = "1.20";
    $Price2 = "1.50";
    $TotalCost = $Price1 + $Price2;

    '$TotalCost' would have the value of "2.7"... I want to be able to print it with a trailing zero on the end of it, so when I print it out it'll be "2.70" rather than "2.7", for example. How do I do this? I'm assuming this involves string/character checks and manipulation but I'm not sure how to go about it.

    Cheers,

    Git

    Does Perl have a printf or pad function?

    To be honest I'm not really sure, as I'm a bit of a newbie at all the functions/etc.. Does anyone know how to do this?

    Cheers,
