This module provides several functions to work with interval-related math.
Namely, the functions in this module can be called from other modules by using require('Module:Interval') and calling the _-prefixed functions.
Functions
to_cents(ratio, prec)returns the measure in cents of an interval ratio, rounded to a precision ofprecdecimal places. Parameterprecdefaults to 3 if it is omitted.parse_ET(input)returns the size (number of divisions) and the equave of an equal tuning given its name. Currently only supports equal divisions (e.g. no 88cET yet). This function is designed to be used by other modules only; it cannot be called with{{#invoke:}}.parse_ET_size(frame)andparse_ET_equaverespectively return the size (number of divisions) and the equave of an equal tuning given its name. This function is designed to be used with{{#invoke:}}only.backslash_ratio(input)returns the ratio corresponding to an interval written in backslash notation.
