windowsnumerics.h APIs

  • Article

The windowsnumerics.h header file defines C++ vector and matrix types in the Windows.Foundation.Numerics namespace. It extends the structs from Windows.Foundation.Numerics with a range of mathematical operators and functions.

This namespace is available only in C++. Its .NET equivalent is System.Numerics.

Topic Description
float2 structure A vector with two components.
float3 structure A vector with three components.
float3x2 structure A 3x2 matrix, used for 2D transforms.
float4 structure A vector with four components.
float4x4 structure A 4x4 matrix, used for 3D transforms.
plane structure This structure represents a plane using a 3D vector normal and a distance value.
quaternion structure A four dimensional vector, used to represent a rotation.
Windows numerics and DirectXMath interop APIs These functions convert Windows.Foundation.Numerics types to and from the DirectXMath SIMD types XMVECTOR and XMMATRIX.
