Function directx_math::XMQuaternionIsNaN

pub fn XMQuaternionIsNaN(Q: FXMVECTOR) -> bool

Test whether any component of a quaternion is a NaN.

Parameters

Q Quaternion to test.

Return value

Returns true if any component of Q is a NaN, and false otherwise.

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.
