remove leading zero in float formatted output

[migurus]

Is it possible to print a float or double and omit the leading zero in
the following fasion:
..123

Code:
float f = 0.1;
printf("%.1f\n", f);
result:
0.1

Is there a trick with format string to get
..1
printed instead?

I don't think you can do it just by changing the format string, as the
standard says "If a decimal-point character appears, at least one
digit appears before it.". Possibly it might help to print the string
to a buffer, using sprintf, and then inspect that before printing it.

Hope that helps.
