In addition to Corona688 reply, you should be aware that there is no way to get an accurate 10 digit precision with floats. You can only expect about 7 digit precision with them. You need to use double precision variables (~ 16 digit precision) instead.

LEARN ABOUT ULTRIX
nl_sprintf
nl_printf(3int) nl_printf(3int)
Name
nl_printf, nl_fprintf, nl_sprintf - print formatted output
Syntax
#include <stdio.h>
int nl_printf ( format [, arg ] ... )
char *format;
int nl_fprintf ( stream, format [, arg ] ... )
FILE *stream;
char *format;
int nl_sprintf ( s, format [, arg ] ... )
char *s, format;
Description
The international functions and are identical to and have been superceded by the international functions and in a library. You should use
the and functions when you write new calls to print formatted output in an international program. For more information on these functions,
see the reference page.
You can continue to use existing calls to the or international functions. These functions remain available for compatibility with XPG-2
conformant software, but may not be supported in future releases of the ULTRIX system.
The and international functions are similar to the standard I/O function. (For more information about the standard I/O function, see the
reference page.) The difference is that the international functions allow you to use the I%digit$ conversion sequence in place of the %
character you use in the standard I/O functions. The digit is a decimal digit n from 1 to 9. The international functions apply conversions
to the n th argument in the argument list, rather than to the next unused argument.
You can use % conversion character in the international functions. However, you cannot mix the % conversion character with the %digit$
conversion sequence in a single call.
You can indicate a field width or precision by an asterisk (*), instead of a digit string, in strings containing the % conversion charac-
ter. If you use an asterisk, you can supply an integer argument that specifies the field width or precision. In strings containing the
%digit$ conversion character, you can indicate field width or precision by the sequence *digit$. You use a decimal digit from 1 to 9 to
indicate which argument contains an integer that specifies the field width or precision.
The conversion characters and their meanings are identical to
You must use each digit argument at least once. The results of not using an argument are undefined.
International Environment
LC_NUMERIC If this environment is set and valid, uses the international language database named in the definition to determine radix
character rules.
LANG If this environment variable is set and valid uses the international language database named in the definition to determine
collation and character classification rules. If is defined, its definition supercedes the definition of LANG.
Examples
The following example illustrates using an argument to specify field width:
nl_printf ("%1$d:%2$.*3$d:%4$.*3$d
",
hour, min, precision, sec);
The format string *3$ indicates that the third argument, which is named precision, contains the integer field width specification.
To print the language independent date and time format, use the following statement:
nl_printf (format, weekday, month, day, hour, min);
For United States of America use, could be a pointer to the following string:
"%1$s, %2$s %3$d, %4$d:%5$.2d
"
This string produces the following message:
Sunday, July 3, 10:02
For use in a German environment, could be a pointer to the following string:
"%1$s, %3$d. %2$s, %4$d:%5$.2d
"
This produces the following message:
Sonntag, 3. Juli, 10:02
