A 2D vector for storing signed, normalized values as signed 8-bits (1 byte) integers.
For a list of additional functionality such as constructors and operators that are available using
XMBYTEN2 when you
are programming in C++, see XMBYTEN2 Extensions.
Signed 8-bit integer value in the range [-127, 127] describing the x-coordinate of the vector.
Signed 8-bit integer value in the range [-127, 127] describing the y-coordinate of the vector.
XMBYTEN2 constructors using floating point arguments require normalized input, which must be in the range of
[0.0.-1.0]. During instantiation, this data is multiplied by 127.0f, results are rounded, and then assigned to the
appropriate members of
XMBYTEN2 can be used to load instances of XMVECTOR from normalized values,
by using XMLoadByteN2, which divides each component 127.0f, rounds the result,
and then assigns the components to an
XMVECTOR instances containing normalized values can be stored into
XMStoreByteN2, which multiplies each component by 127.0f, rounding the result, before assigning
the values to the appropriate
