[erlang-questions] math:pow(X, Y).

That's the standard method that I use to raise a value to a power. I
compared this to the way Python does raising to a power and this is the
result that I get:
11> math:pow(42, 909).
** exception error: bad argument in an arithmetic expression
in function math:pow/2
called as math:pow(42,909)
Now. Why is it in Erlang's case I get a float as a return value? Is there
a method that only returns a long? Or do most erlang coders have a custom
power function if they want ridiculously large numbers?
