A 2D vector for storing unsigned, normalized values as signed 8-bits (1 byte) integers.
For a list of additional functionality such as constructors and operators that are available using
XMUBYTEN2 when you
are programming in C++, see XMUBYTEN2 Extensions.
Unsigned 8-bit integer value in the range [0, 255] describing the x-coordinate of the vector.
Unsigned 8-bit integer value in the range [0, 255] describing the y-coordinate of the vector.
XMUBYTEN2 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 255.0f, results are rounded, and then assigned to the
appropriate members of
XMUBYTEN2 can be used to load instances of XMVECTOR from normalized values, by using
XMLoadUByteN2, which divides each component 255.0f, rounds the result, and then assigns the
components to an
XMVECTOR instances containing normalized values can be stored into
XMStoreUByteN2, which multiplies each component by 255.0f, rounding the result, before assigning
the values to the appropriate
