> There are quite a few programming languages that provide support for numeric types apart from the customary floating-point and fixed-width integer types. Prominent examples of additional numeric types include rational numbers, arbitrary-width integer types, and fixed-point numbers. Many of these numeric types are applicable to a wide variety of problem domains.<br>

Structs and value semantics, literal initialization, and operator overloading would allow such types to be treated as first-class citizens. Is the community amenable to such a proposal, which would entail the data structures themselves, arithmetic operations, and interoperation between different numeric types to form a numerical tower of sorts?<br>

</span>Hi Austin,<br>
<br>
We are interested in improving our numerics support, and we are<br>
definitely interested in hearing your ideas in this space. You don't<br>
have to write a full proposal though. Just an extended email to<br>
swift-evolution would be a good start.<br>
<br>
You can find the current prototype for library support for integers<br>
