howto format currency string?

[adegreiff]

hi,

using zope/pythons/page templates i need to format a float number to a
string like 10,250.10

(note the thousand separator and the trailing zero in the decimal)

i was able to use %0.2f bit that returned no thousand separator.
i was able to use thousands_commas function but that returned
"10,250.1" which is wrong.

any ideas?

thanks
alexander
