getMicroFMeasure() gives not the same value as getAccuracy()
Thanks for reporting! Good catch - do you have a MWE? Or even better a reference (paper, textbook, or similar) which can be turned in a unit test?
I looked to the code and for a first look, I didn't find something wrong - maybe it is a rounding/java number preciseness issue somewhere, the numbers doesn't have a huge difference. This is my example which goes wrong acc 0.3225806451612903 vs microF 0.367816091954023:

Sorry for just pasting it
