you don't mean commas but thousands' grouping???
if you want thousands' grouping it depends on your locale setting!

For some numeric conversion a radic character (`decimal
point') or thousands' grouping character is used. The
actual character used depends on the LC_NUMERIC part of
the locale. The POSIX locale uses `.' as radix character,
and does not have a grouping character. Thus,
printf("%'.2f", 1234567.89);
results in `1234567.89' in the POSIX locale, in
`1234567,89' in the nl_NL locale, and in `1.234.567,89' in
the da_DK locale.
