This is one of many areas that we haven’t had time to really think about (specifically, how far the math portion of the Swift stdlib should go). I think there is some general sentiment (e.g. expressed by Steve Canon) that Swift should eventually provide BigInt and robust decimal floating point support, but given the Swift 4 Stage 1 challenges in front of the standard library, we need to keep focused on that. Extensions like that can be added at any time.
However, this isn’t something that really needs to be debated here: I’d strongly encourage you to start a project (e.g. on github) and try to build out some interesting things. Once you have something interesting that works well, we can talk about whether it makes sense to incorporate some of the code or ideas into Swift, or whether it makes sense to be a standalone library.
