Hello,

The way you "force (a scalar) to float context" in perl is simply use it in numeric context (construct an expression that would require the scalar be used as a number). So the += 0 stuff isn't necessary.

Anywhoo, what you are trying to do works fine in general so you have something funky going on in your code, and you haven't given us enough information to suggest a solution:

$ perl
use warnings;
use strict;

my $retail_rate = 109.98;
my $coupon = 10.05;
my $discounted_rate = $retail_rate + 1;
print "$retail_rate $coupon $discounted_rate\n";
Ctrl-D
109.98 10.05 110.98

Hope this helps,
