K 10 svn:author V 3 das K 8 svn:date V 27 2003-04-05T22:11:42.000000Z K 7 svn:log V 623 Rework the floating point code in printf(). Significant changes: - We used to round long double arguments to double. Now we print them properly. - Bugs involving '%F', corner cases of '#' and 'g' format specifiers, and the '.*' precision specifier have been fixed. - Added support for the "'" specifier to print thousands' grouping characters in a locale-dependent manner. - Implement the __vfprintf() side of hexadecimal floating point support. All that is still needed is a routine to convert the mantissa to hex digits one nibble at a time in the style of ultoa(). Reviewed by: silence on standards@ END
