--- Comment #2 from Javen O'Neal <on...@apache.org> ---
Could you make your test case for -2^(1/2) and -2^(0.5) to show that the
problem isn't with order of operations in the exponent but in the sign
association with the base?

The mathematicians among us will also appreciate that x^0.5 is the same as
sqrt(x).
