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

[Yves S. Garret]

Hi all,

   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:

Erlang:
11> math:pow(42, 909).
** exception error: bad argument in an arithmetic expression
     in function  math:pow/2
        called as math:pow(42,909)

Python:
http://bin.cakephp.org/view/1006418268

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?
