how do I format number with leading zero?

[bunner_bob]

I have a calculation that adds two 2-digit numbers together. Sometimes the result is less than 10 (i.e. 0-9) and I'd like the answer to be formatted with a leading zero (i.e. 00-09).

Is there an easy way to do this?

Otherwise I'll just check for whether it's 0-9, and echo an extra "0" in front, which seems clunky but I guess it'll work.

check out sprintf();

Ahh - that's it. Knew there was something more elegant.

Thanks!
