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. |
