Apparently, bid128_pow() does not handle integer exponents specially. I'll fix that by transplanting the repeated-squaring logic for the complex case. 10^-31 not being exact, sheesh!
Assuming nothing else is wrong, Free42 Binary should be OK, if you throw large negative powers of 2 at it. As far as I know, the libc pow() does use repeated squaring for integer exponents.
