Hi,

does anybody know whether there is a freely available somewhere a
function for printing floats in a way similar to the %g
argument of printf? E.g.:

printf("%g\n",0.02); [C]
results in
0.02

print, 0.01 [IDL]
0.0100000

(no extra blanks, no extra zeroes)

Of course, I could say in IDL

print,format='(f4.2)',0.01

but I need something that, without knowing the number of
digits in advance, makes an earnest effort to save space
and keep readability (and works, e.g., also with 0.003!!!)

Thanks in advance,
Andrea Spinelli
