FixedPointNano

FixedPointNano is a small C# library for representing fixed-point numeric values using an Int64 scaled to 9 decimal places.

Design

  • Storage type: long
  • Scale: 1_000_000_000
  • Precision: 9 decimal places
  • Target runtime: .NET 10

The library is intended for domains where deterministic 9-decimal fixed-point values are preferred over binary floating-point storage.

Features

  • Deterministic long-backed storage
  • Conversion operators for .NET numeric types
  • IConvertible support
  • Standard numeric formatting via ToString(...) and TryFormat(...)
  • Raw scaled arithmetic and comparison operators
  • Fast helper methods for Square, Sqrt, population variance/standard deviation, integer division, and ratio multiplication
  • Explicit finite-only double conversion with nano-scale rounding

Example

using Seerstone;

var price = (FixedPointNano)123.456789123m;
var quantity = (FixedPointNano)2;
var total = price * quantity;
var average = FixedPointNano.Divide(total, 2);
var volatility = FixedPointNano.Sqrt(FixedPointNano.Square(price - average));

Console.WriteLine(total.ToString("F9"));

Benchmarks

BenchmarkDotNet microbenchmarks live under benchmarks/FixedPointNano.Benchmarks. They compare FixedPointNano raw math against decimal-reference and double-reference paths. Run a short local pass with:

dotnet run --project benchmarks/FixedPointNano.Benchmarks/FixedPointNano.Benchmarks.csproj -c Release -- --filter "*" --warmupCount 1 --iterationCount 1
