Produce two unsigned integers containing the bit encoding of a double precision floating point value.
||-||Specifies double precision value to break into a pair of unsigned integers.|
unpackDouble2x32 returns a two-component unsigned integer vector representation of
d . The bit-level representation of
d is preserved. The first component of the returned vector contains the 32 least significant bits of the double; the second component consists the 32 most significant bits.
