packDouble2x32 — create a double-precision value from a pair of unsigned integers
double packDouble2x32( | uvec2 v); |
v Specifies a vector of two unsigned integers to be packed into a single double-precision result.
packDouble2x32 packs the component of parameter v into a 64-bit value. If an IEEE-754 infinity or NaN is created, it will not signal and the resulting floating-point value is undefined. Otherwise, the bit-level representation of v is preserved. The first vector component (v[0]) specifies the 32 least significant bits of the result; the second component (v[1]) specifies the 32 most significant bits.
