real-accurate, numpy...increased precision help

[Bryan Webb]

I need to be able to work with numbers up to 2^800 in a floating point
envirnoment. I would like an increase of precision over std floats. I also
would like to know the internal representation of the numbers, so that I can
read and write them to disk in their internal representations..
Should I use real-accurate, or numpy
Any help would be appreciated
Thanks for the help
