Numeric Formatting Routines - HP 9000 User Manual

Note
Although the form of the new language-sensitive character
identification routines does not differ from the "ASCII only"
routines, the type of argument passed has changed from char
to into When passing 8-bit bytes to these routines, the data
should be unsigned char, or cast to it, to ensure correct sign
extension.
Numeric Formatting
The numeric formatting routines (for example, ecvt, gcvt, atof, printf,
and fprintf) have been internationalized and give locale-sensitive results for
single-byte and multi-byte data. For information about restrictions on the use
of multi-byte data, see
ecvt(3C), strtod(3C),
and
printf(3C)
in Section 3 of the
HP-UX Reference.
