XMSHORTN2 structure (directxpackedvector.h)
A 2D vector for storing signed, normalized values as signed 16-bit integers (type
int16_t
).
For a list of more functionality such as constructors and operators that are available
using XMSHORTN2
when you are programming in C++, see XMSHORTN2 Extensions.

void XMSHORTN2( int16_t _x, int16_t _y) noexcept
Initializes a new instance of XMSHORTN2
from two int16_t
arguments.
This constructor initializes a new instance of XMSHORTN2 from two
int16_t
arguments.
void XMSHORTN2( const int16_t *pArray) noexcept
Initializes a new instance of XMSHORTN2 from a two element int16_t
array argument.
This constructor initializes a new instance of XMSHORTN2 from a two element int16_t
array argument.
void XMSHORTN2( float _x, float _y) noexcept
Initializes a new instance of XMSHORTN2

XMSHORTN2 & operator=( uint32_t Packed) noexcept
Remarks
Those 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
members of XMSHORTN2
.
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
XMVECTOR
instance.
You can store XMVECTOR
instances containing normalized values into XMSHORTN2
using XMStoreShortN2, which multiplies each component by 32767.0f,
rounding the result, before assigning the values to the appropriate XMSHORTN2
members.
