System.Runtime.Numerics

Contains additional numeric types that complement the numeric primitives (such as Byte, Double, and Int32) that are defined by .NET. This includes:

• The BigInteger structure, which is a non-primitive integral type that supports arbitrarily large integers.
• The Complex structure, which represents a complex number. A complex number is a number in the form a + bi, where a is the real part, and b is the imaginary part.
• The SIMD-enabled vector types, which include Vector2, Vector3, Vector4, Matrix3x2, Matrix4x4, Plane, and Quaternion.

Documentation can be found here: https://learn.microsoft.com/en-us/dotnet/api/system.numerics.

This area also includes all of the interfaces that make up Generic Math, which is discussed more here: https://learn.microsoft.com/en-us/dotnet/standard/generics/math.
