Computes the magnitude of a quaternion.

Syntax

XMVECTOR XM_CALLCONV XMQuaternionLength(
  [in] FXMVECTOR Q
) noexcept;

Parameters

[in] Q

Quaternion to measure.

Return value

Returns a vector. The magnitude of Q is replicated into each component.

Remarks

The DirectXMath quaternion functions use an XMVECTOR 4-vector to represent quaternions, where the X, Y, and Z components are the vector part and the W component is the scalar part.

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
