>Environment:
Linux Mandrake 8 and 8.1
Kernel 2.4.6-26mdk - but other versions of the kernel give the same results.
gcc version 2.96 (Linux-Mandrake 8.0 2.96-0.48mdk) and 3.0
>Description:
The %g output format specifier does not display zeros as significant figures. This is not correct because a zero is generally displayed if it is accurate. For example a value of 1 should be displayed as '1.0' to two significant figures (%.2g) because the zero is accurate, but it displays it as '1'. The %f output format specifier does not have this problem and displays zeros as necessary (1 will display as 1.0 under %.1f).
>How-To-Repeat:
Compile the sample program and run it!
I used 'gcc -o test test.c' to compile it.
>Fix:
Don't know... I was hoping some kind soul out there would help.
