Let me try that again, this time with code that compiles and in a more
friendly tone :)

Uh, not where I tested [AIX 5.3, XL C/C++ V9.0].
$ cat t.cpp
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char* argv [])
{
const float f = 1 < argc ? atof (argv [1]) : 1.1;
printf ("%g\n", f);
printf ("%.0g\n", f); // should be same as %.1g
printf ("%.1g\n", f);
printf ("%.2g\n", f);
printf ("%.3g\n", f);
printf ("%.4g\n", f);
printf ("%.5g\n", f);
printf ("%.6g\n", f);
printf ("%.7g\n", f);
printf ("%.8g\n", f);
printf ("%.9g\n", f);
return 0;
}
$ xlC t.cpp && a.out 1.1
1.1
