Ok, but math.pow IMPO has to be aligned to pow and built-in pow (**), otherwise this kind of "inaccuracies" can compromise the application behavior. I was using this funcion in a cryptographic mechanisms, and this issue resulted in a failure. 
Generally speaking, integer numbers should not be affected by inaccuracies. I mean, there's no floating point.
