Re^2: Negative zero? There's gotta be a sprintf that undoes that, right? (0+"$x")

Ahh... but further testing shows that

printf "%f\n", 0+"-0.0";
0.000000
printf "%f\n", 0+"-0.00000009";
-0.000000

I have a feeling this has to do with something lower than actual negative zero being numerified as a negative number, THEN going through printf, which undoes all that extra work.
