Use FloatMath instead of Math when generating Sine table

Galaxy s4 seems to suck balls at calculating Sine extremely quickly. If
it is called too rapidly, it'll just return 0s. this is terrible.
FloatMath seems to work although it is a performance hit. hopefully,
since this is only run on instrument setup, it shouldn't really affect
performance
