A 25-bit fractional part for microtonal precision, expressed in base 32 using the characters 0–9 and A–V. This base-32 representation spans values from 00000 (zero fraction) up to a maximum that encodes all 2^25 subdivisions of a semitone. | A 25-bit fractional part for microtonal precision, expressed in base 32 using the characters 0–9 and A–V.
