Hi, I just want to say i've been searching around this forum and have seen things about GMP and precision arithmetic (which im reading now).

However, i've seen nothing to the extreme of a number that I need. This is an *extremely* large number.

Before I even get into the specifics, ill write an example of how large it is.

2^x

where x is a power that is about 20,000 digits long. Is this even remotely possible for a regular computer? Thanks.
