System.Numerics Namespace

The System.Numerics namespace contains numeric types that complement the numeric primitives, such as Byte, Double, and Int32, that are defined by the .NET Framework.

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, such as Vector4, Matrix3x2, Plane, and Quaternion.

  Structure Description
Public structure Supported by Portable Class Library BigInteger Represents an arbitrarily large signed integer.
Public structure Supported by Portable Class Library Complex Represents a complex number.
Public structure Matrix3x2 Represents a 3x2 matrix.
Public structure Matrix4x4 Represents a 4x4 matrix.
Public structure Plane Represents a three-dimensional plane.
Public structure Quaternion Represents a vector that is used to encode three-dimensional physical rotations.
Public structure Vector2 Represents a vector with two single-precision floating-point values.
Public structure Vector3 Represents a vector with three single-precision floating-point values.
Public structure Vector4 Represents a vector with four single-precision floating-point values.
