Omitted from the original table are operands, enclosures, spaces, big/long variants, and non-NFKC characters. Three characters that default to their emoji variants on iOS, and one related character, are excised.

The design, re-design, and implementation of [SE-0104][1], a proposal to revise integer protocols in Swift, is now largely complete in shipping previews of Swift 4. As an exercise, I have used the new APIs to develop a [set of additional numeric facilities][2]. Here are some insights gained from that experience--and from two unpublished exercises to implement a BigInt type (one from scratch, one wrapping GMP)--as well as suggestions for improvement.
protocol Arithmetic : Equatable, ExpressibleByIntegerLiteral
An type that provides certain arithmetic operations (addition, subtraction, and multiplication).
Types that conform to Arithmetic
satisfy the following conditions for any values a
, b
, and c
(unless the result of an operation overflows the maximum size of the conforming type):
+
) is commutative; that is, a + b == b + a
We propose to complete Swift's suite of range operators to introduce a fully open range (<.<
) and the second complementary half-open range (<..
).
