Meta.Numerics is library for advanced numerical computing on the .NET platform. It offers an object-oriented API for statistical analysis, advanced functions, Fourier transforms, numerical integration and optimization, and matrix algebra.

General purpose C# code library.

Efficient numerics for the jvm

SG⁺⁺ – the numerical library for Sparse Grids in all their variants.

Numeric facilities for Swift

A complete, proof-of-concept, C# implementation of the General Number Field Sieve algorithm for factoring very large semi-prime numbers. The focus was on readability and understandability of the code, not performance.

An arbitrary-precision decimal (base 10) floating-point number class. Over 2.5 million downloads on NuGet!

A number format that inspects your code by logging the arithmetic results.

A dependency free, lightweight, fast math library for 2D and 3D vectors, quaternions and matrices in Swift with (optional) SIMD support.

The main project for the MATLAB / GNU Octave code of FESTUNG

Linear algebra done rigorously

A .NET library that provides strongly-typed implementations of multiple coordinate systems, including rectangular, polar, spherical, and geodetic.
