Important music21 function for working with offsets and quarterLengths Takes in a number and converts it to a Fraction with denominator less than limitDenominator if it is not binary expressible; otherwise return a float. Or if the Fraction can be converted back to a binary expressible float then do so. This function should be called often to ensure that values being passed around are floats and ints wherever possible and fractions where needed. The naming of this method violates music21's general rule of no abbreviations, but it is important to make it short enough so that no one will be afraid of calling it often. It also doesn't have a setting for maxDenominator so that it will expand in Code Completion easily. That is to say, this function has been set up to be used, so please use it. This is a performance-critical operation. Do not alter it in any way without running many timing tests. >>> from fractions import Fraction >>> defaults.limitOffsetDenominator 65535 >>> common.opFrac(3) 3.0 >>> common.opFrac(1/3) Fraction(1, 3) >>> common.opFrac(1/4) 0.25 >>> f = Fraction(1, 3) >>> common.opFrac(f + f + f) 1.0 >>> common.opFrac(0.99999999842) 1.0 >>> common.opFrac(0.123456789) Fraction(10, 81) >>> common.opFrac(0.000001) 0.0 Please check against None before calling, but None is changed to 0.0 >>> common.opFrac(None) 0.0 * Changed in v9.3: opFrac(None) should not be called.
