In fairness, the general power function might well be complicated. Dealing with fractional base and exponent, signs (-1^2 makes sense but -1^0.5 doesn't in real

In fairness, the general power function might well be complicated. Dealing with fractional base and exponent, signs (-1^2 makes sense but -1^0.5 doesn't in real numbers). I don't know how that works in code but I can see how this gremlin sneaks in. I don't see how it gets past the test suite though.
