Re: computing fractions

A really basic math question:

I'm trying to compute values like 2^-30000 (in base 10
representation). I'd like to get the decimals directly, without
dividing a bignum 40000 times to get 2^-40000 etc.

There oughta be some smarter way? (Say, O(log N) rather than
O(N)...) A general method (for any number base) would be cool,
but I'm also all ears if there's some special method for power
of 2 fractions.

The right terminology so I can find it with google/wikipedia
may be all I need...
