How to zero-pad hex values in sprintf()?

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

It's of academic interest because I can always check length and add the zero myself but, am I crazy or do printf() and sprintf() have no way to return, say, 0F instead of just F?

Thanks to everyone who posted. I feel rather foolish. Somehow I was adding the zero for the padding but missing the number. I need more sleep.	[reply]
