Why not using `java.lang.Math.pow(x,y)` directly in `SimpleMath`?

Why not using java.lang.Math.pow(x,y) directly in SimpleMath?
Is there a real advantage to use a specialized method for the int argument?

Good question. I think I did backtests a while ago that showed exponentiation by squaring was much faster than pow(x, y) for integer argument. However, this was a very long time ago and it may no longer be so. If you wish to simplify dependencies then pow is perfectly acceptable.
