Alex Herbert commented on NUMBERS-151:
--------------------------------------

In this case we will support {{0^0 == 1}} as per the wikipedia article on the subject: 

[Zero to the power of zero|https://en.wikipedia.org/wiki/Zero_to_the_power_of_zero]

> Hi.
> right now ArithmeticUtils.pow(0,0) = 1, but not throw an Exception, which I think not quite right...
> Is it a bug?
> Anyway, we found a way to faster the calculate, so at least we can get an performance refine pr.
