Right, this functionality would not solve the semitones / cents problem. Nor will it achieve world peace. But if it solves enough use cases then it is worth discussing, yes?
I haven't written the string parsing, but once we know that "0.001" means to look in [0.0005, 0.0015) then we can invoke the attached as best_fraction(Fraction("0.001"), Fraction("0.0005"), Fraction("0.0015")) to get the output Fraction(1, 1000).
