Almost: though this works for the last example, it breaks the one before the last (I'm looking for a format specifier that would constrain the number of decimals, not the number of digits, so that (format "%.3q" 30.352) would produce "30.35" — maybe all these examples should have had %.2q instead of %.3q, in fact).
