Details

- IntegerDigits gives the most significant digit first, as in standard positional notation.
- IntegerDigits[n] discards the sign of n.
- If len is less than the number of digits in n, then the len least significant digits are returned.
- IntegerDigits[0] gives {0}.
- FromDigits can be used as the inverse of IntegerDigits.
