float_to_list(X)

[Eckard Brauer]

For that purpose it makes maybe more sense to show a sort of "hybrid"
representation of the form floats are usually represented in memory:

s 1.mmmm e xxxx

where

s    is signum ("-", "+" or empty),
mmmm    is mantissa, in hex, oct or bin to effectively express all
relevant digit positions (with removed trailing zeroes),
xxxx    is exponent with possible "-" and also all digits needed.

That would be both human readable and provide some metric, while still
keeping some compactness (maybe not really true for the binary form)
and unambiguousness.

Just my 2 cents.
