Moin, I'm looking for some algorithms to get arbitrary roots of numbers other irrational numbers. these numbers should be at least 100000 digits long. What i really want is a distribution of the numbers 0..9. Therefor i allready got a ruby-script, but to produse such long numbers seems to be difficult. Till now i use the 'pi.rb' from the samples inside the ruby source, fibonaccis and e, generatet with the bigfloat-extension from raa. Does anyone know a good source for such algorithms (no matter which lang)? thanks ralf ------------------------------------
