Function directx_math::XMQuaternionIsNaN [−][src]
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.
