Isn't the precision of a float 8 decimal digits?
.dig reports 6

Why isn't "%.100g" cropped to the max decimal digits of the accompanying
type?
floating point types are printed with 20 digits.

I just want to format in full precision.
As far as I can see 6 digits is not the full precision
e.g. 0x7EAAAAAB = 1.1342746e38
