Decimal and Exponentiation

[elventear]

Hi,

I am the in the need to do some numerical calculations that involve
real numbers that are larger than what the native float can handle.

I've tried to use Decimal, but I've found one main obstacle that I
don't know how to sort. I need to do exponentiation with real
exponents, but it seems that Decimal does not support non integer
exponents.

I would appreciate if anyone could recommend a solution for this
problem.

Thank you.
