0 raised to power of n, where n is negative number with more than 15 digits returns 0 (not Infinity) #338

Repro steps:

import BigNumber from "bignumber.js";

console.log(new BigNumber(0).exponentiatedBy('-123456789012345').toString()) // Returns Infinity (ok).
console.log(new BigNumber(0).exponentiatedBy('-12345678901234567890123456789012345678901234567890').toString()) // Returns 0 (seems like not ok).

It seems to me, that this behavior is somewhat inconsistent and zero raised to power of negative number should return Infinity independent from power's length.

Yes, it's a bug. Thanks for the report. I'll see to it presently.

Fixed in v9.1.1.
