[in] V

Vector to test.

Return value

Returns a vector containing the results of each component test.

Remarks

The following pseudocode demonstrates the operation of the function:

XMVECTOR Result;

Result.x = (V.x == +infinity || V.x == -infinity) ? 0xFFFFFFFF : 0;
Result.y = (V.y == +infinity || V.y == -infinity) ? 0xFFFFFFFF : 0;
Result.z = (V.z == +infinity || V.z == -infinity) ? 0xFFFFFFFF : 0;
Result.w = (V.w == +infinity || V.w == -infinity) ? 0xFFFFFFFF : 0;

return Result;
