        <h2>Description</h2>
        <p>
            <code class="function">unpackHalf2x16</code> returns  a two-component floating-point vector with
            components obtained by unpacking a 32-bit unsigned
            integer into a pair of 16-bit values, interpreting those
            values as 16-bit floating-point numbers according to the
            OpenGL ES Specification, and converting them to 32-bit
            floating-point values.
            The first component of the vector is obtained from the
            16 least-significant bits of v; the second component is
            obtained from the 16 most-significant bits of v.
