I have looked all over the place and have yet to find an answer to this question: I am using sprintf and am trying to print out numbers formatted with comma separators. I have tried:
 - setlocale
 - putting a tick (%'.02f) into the format string

Am I missing something? Also, I can't use the number_format function.

Thanks in advance.

Wow, no response at all. Is this not possible with sprintf?
