That's because ** calls the pow function and that function evaluated
all non-integer exponents the same way (exp (log(a) * b)). I've changed
that function to recognise powers of 1/2 and 1/3 and call sqrt and cbrt.

There was a bug in the compiler that compiled the operands in the wrong
Thanks for your bug reports!
