Compute Integer to Any Real Power Algorithm

[michalll]

Hi, I was wondering if there exists an algorithm for one by one digit computation of an integer to the power of any real number? Couldn't find anything on the net.

There are digit-by-digit algorithms for square roots and even cube roots. But nobody uses them any more, not even computers use them. If they are not on the Internet, then you may have to go and look in an old-fashioned paper book. (You know, the kind copied by ancient monks using pens made from goose quills.)
