printf formatting in regular expressions?

bunnym4n has asked for the wisdom of the Perl Monks concerning the following question:

How would I go about doing a printf format of a var within a s/// expression? I'm using a template for a reporting module, but I need to format vars as %.2f within a s/// statement. Any help would be greatly appreciated, oh wise monks.

Use sprintf and the /e switch on the regex: `s/(\d+)/sprintf '%04d', $1/e` [download] Perl reduces RSI - it saves typing	[reply] [d/l]
