🐛 Exponential operator(^) does not throw exception about overflow

[seungukson]

First of all, thanks for your code. I found a bug, and would like to report it

It's about exponential(^) operation between two bigDecimal number. I think that a calculation which expected to take a long time to calculate must throw exception about overflow. e.g. Expressions().eval("34^3.0E+24") Expressions().eval("34^3.0E+2451223111")

The code above throw exception about overflow. But below is not 34^3.0E+2451223

I think it has to have some validation about each power calculation. Thank you
