#include <stdio.h>
int main (void)
{
double a = 1.0;
double b = 0.9999999999999999;
printf("%#12.5g\n", a);
printf("%#12.5g\n", b);
return 0;
}
The above produces as output:
1.0000
1.00000
According to the C standard it should produce
1.0000
1.0000

I just updated to glibc 2.5 plus patches from CVS as made
available by LFS, and the problem is still there.
Is this fixed in 2.6, and if so is there a release date
in mind for that? Thanks.
