This format has a few limitations; it can get ambiguous if you also need
higher resolution (more than two digits) and higher values (more than 9
zeroes). In both cases, you'd add an additional digit, but in one case it's
part of the number (as with resistors), in the other it's part of the
exponent. Could probably be resolved by resorting to letters for the
exponents beyond 9, which would leave the exponent as always the last
character.

But I still think the traditional SI style is pretty clear, flexible, and
succinct too. And it looks... don't know, maybe "nice"? :)
