Specialized and inlined versions of arithmetic operators.
include module type of struct include Stdlib.Int end(divisible n) is that function of u that returns true iff u is evenly divisible by n, with no remainder.
(digits ?base n) is the number of digits required to express n in base (default base: 10). The number of digits in a negative number does not include the sign.
(missing ints) return the integers that are missing in ints; tail-recursive.
I.e., return the list of integers between (minimum ints) and (maximum ints) that are not in ints.
