What is FixedPoint?

FixedPoint delivers high performance fixed point decimal arithmetic in Swift, fixing precision errors from Double (like inexact 0.1) and Foundation.Decimal's variable-precision slowdowns. It locks 8 fractional digits into a single Int64 for exact math on prices, quantities, and FX rates—zero heap allocations across add, mul, div, and conversions. Install via Swift Package Manager for Linux, Apple platforms, ARM/x86.

Why is it gaining traction?

Crushes Decimal: 359x faster adds, 168x divs, 900x comparisons per M4 benchmarks, all inlining-friendly with @frozen layout. Codable JSON as strings (ints/doubles decode too), SwiftUI animations, Charts plotting, atomic concurrency—banker's rounding unifies parsing/arithmetic/UI. Beats fixed point python or fixedpoint sol overhead in pure Swift speed.

Who should use this?

Swift finance devs pricing trades, crypto satoshis, or basis points without Double drift. iOS/macOS apps charting high performance fixed point data in SwiftUI. Backend services swapping slow Decimal for github high performance wins on high availability servers.

Verdict

Grab it for decimal-heavy apps craving speed—benchmarks sell it. Low 11 stars/1.0% credibility score means watch for edge cases, but 541 tests, fuzzing, and DocC docs build trust fast.
