Fellow monks,

I'm in the process of writing a stock tracking program that uses sprintf to display the percent change in a given stock to 3 decimal places. However when I use sprintf "%.3f", if my number is 0.010, I'm getting the trailing 0 like I expect since I've set it to 3 decimal places.

What I'd like to do is to get rid of trailing zeros. I've looked over the docs on sprintf and can't find a way to do it. My solution at present is the following: 

$percent_change = sprintf "%.3f", $percent_change;
$percent_change =~ s/0+$// if $percent_change =~ /0+$/;

That code works, but it seems a bit of a workaround. Have I missed something somewhere in my use of sprintf?

There is no emoticon for what I'm feeling now.
