Locale question

[Michael Meskes <meskes@debian.org>]

I never cared much about localization but now I'm stuck with a program that
works well with all locales but has to do some output without using the
locale.

Since the output is a floating point I get e.g. 14,7 instead of 14.7 using
the german locale. But I need it to output 14.7. So far it uses printf for
output. Is there a printf-like-function that does not care about locales? Or
a format string that is locale-independant? Or is the only solution to
setlocale(LC_ALL, "C") before the printf and setlocale(LC_ALL, "de_DE")
afterwards?
