2004-07-29 Paolo Carlini <pcarlini@suse.de>

	PR libstdc++/14220
	* include/bits/locale_facets.tcc (num_put<>::_M_insert_float):
	Don't clip the precision passed down to __convert_from_v:
	22.2.2.2.2 nowhere says so.
	* testsuite/22_locale/num_put/put/char/14220.cc: New.
	* testsuite/22_locale/num_put/put/wchar_t/14220.c: Likewise.
