uintpackHalf2x16(vec2v);

packHalf2x16 returns an unsigned integer obtained by converting the components of a two-component
       floating-point vector to the 16-bit floating-point representation found in the OpenGL Specification, and
       then packing these two 16-bit integers into a 32-bit unsigned integer. The first vector component
       specifies the 16 least-significant bits of the result; the second component specifies the 16
       most-significant bits.

v
           Specify a vector of two 32-bit floating point values that are to be converted to 16-bit
           representation and packed into the result.
