unpackHalf2x16 — convert two 16-bit floating-point values packed into a single 32-bit integer into a vector of two 32-bit floating-point quantities
Specify a single 32-bit unsigned integer values that contains two 16-bit floating point values to be unpacked.
unpackHalf2x16 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
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.
