IntegerDigits

IntegerDigits[n] gives a list of the decimal digits in the integer n.

IntegerDigits[n, b] gives a list of the base-b digits in the integer n.

IntegerDigits[n, b, len] pads the list on the left with zeros to give a list of length len.

Examples: IntegerDigits[5810] ; IntegerDigits[5810, 16] .

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.

FromDigits can be used as the inverse of IntegerDigits.
