I am writing a cryptography program that converts a sting of plaintext into ciphertext. One of the things it needs to be able to do if calculate the irrational real quotient of a devision problem to to several thousand places (around 5,000). Is c++ capable of doing this? If so, how do I write code that will allow me to do this? If not, any suggestions as to any other languages that can do this? Thanks.
Not natively, I don't think any digital computer can. BUT all hope is not lost, look up big integer, and see if that gets you started on writing an ultra precision decimal class.
