For reals, you can use limits/continuation as argument.
The problem with that is that you get two different answers:
lim x^y = 0
x->0
but:
lim x^y = 1
y->0
So it's not clear what ought to happen when both x and y
approach 0.
[...]
First: lim x^x = 1
x->0
Second: Just look at Wikipedia and take the IEEE floating point
standard:
