How about using [makefilename %.8g] ?
Together with the current bugs in atom_string, those symbols will be saved
as full-precision floats that Pd will understand.
%.6g gives 6 decimals of precision = max 19.93 bits
%.7g gives 7 decimals of precision = max 23.25 bits
%.8g gives 8 decimals of precision = max 26.57 bits
to get full precision you need %.8g, because in float32, you have 24 bits
of precision, which is why 16777215 is an exact float32 number, for
example, while 16777217 is not.
