## What it is
Swift Numerics is an Apple-maintained Swift package providing advanced mathematical types and functions such as complex numbers for numerical computing. Its fine-grained modules are candidates for eventual inclusion in the Swift standard library.

## Use cases
- do complex number arithmetic in Swift
- numerical computing library for Swift
- compute trigonometric functions with advanced math types
- add math utilities to a SwiftPM project
- scientific computing in Swift

## When to choose
- you need complex numbers or specialized math types in Swift
- you want a dependency-light, source-stable numerics package
- you want API likely to match future Swift standard library additions

## Facets
- artifact type: library
- maturity: active
- function: math
- domain: mathematics, developer-tools
- platform: cross-platform
- tags: complex-numbers, numerical-computing, swiftpm, apple, swift
