A 2D vector for storing signed, normalized values as signed 16-bit integers (type
For a list of more functionality such as constructors and operators that are available
XMSHORTN2 when you are programming in C++, see XMSHORTN2 Extensions.
Signed integer in the range [-32767, 32767] describing the x coordinate of the vector.
Signed integer in the range [-32767, 32767] describing the y coordinate of the vector.
XMSHORTN2 constructors using floating point arguments require normalized input,
which must be in the range of [-1.0.-1.0]. During instantiation, data is
multiplied by 32767.0f, results are rounded, and then assigned to the appropriate
You can use
XMSHORTN2 to load instances of XMVECTOR from
normalized values by using XMLoadShortN2, which divides each
component 32767.0f, rounds the result, and then assigns the components to an
You can store
XMVECTOR instances containing normalized values into
using XMStoreShortN2, which multiplies each component by 32767.0f,
rounding the result, before assigning the values to the appropriate
