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
vec2 unpackHalf2x16( | uint v); |
v 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 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.
