System.Numerics Namespace

Contains numeric types that complement the numeric primitives, such as Byte, Double, and Int32, that are defined by .NET.

Classes

BitOperations	Provides utility methods for intrinsic bit-twiddling operations. The methods use hardware intrinsics when available on the underlying platform; otherwise, they use optimized software fallbacks.
Vector	Provides a collection of static methods for creating, manipulating, and otherwise operating on generic vectors.

Structs

BigInteger	Represents an arbitrarily large signed integer.
Complex	Represents a complex number.
Matrix3x2	Represents a 3x2 matrix.
Matrix4x4	Represents a 4x4 matrix.
Plane	Represents a plane in three-dimensional space.
Quaternion	Represents a vector that is used to encode three-dimensional physical rotations.
TotalOrderIeee754Comparer<T>	Represents a comparison operation that compares floating-point numbers with IEEE 754 totalOrder semantic.
Vector<T>	Represents a single vector of a specified numeric type that is suitable for low-level optimization of parallel algorithms.
Vector2	Represents a vector with two single-precision floating-point values.
Vector3	Represents a vector with three single-precision floating-point values.
Vector4	Represents a vector with four single-precision floating-point values.

Remarks

This namespace includes the following types:

• The BigInteger structure, which is a nonprimitive integral type that supports arbitrarily large integers. An integral primitive such as Byte or Int32 includes a MinValue and a MaxValue property, which define the lower bound and upper bound supported by that data type. In contrast, the BigInteger structure has no lower or upper bound, and can contain the value of any integer.

• 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.
