Number Digits

The Wolfram Language can handle numbers of essentially unlimited length, in any base, using state-of-the-art platform-optimized algorithms, including several developed at Wolfram Research. For rational numbers, it uses number theoretic methods to efficiently find the exact forms of repeating digit sequences.
