# unpackDouble2x32

## Name

unpackDouble2x32 — produce two unsigned integers containing the bit encoding of a double precision floating point value

## Declaration

`uvec2 unpackDouble2x32(` | double d`)`;

## Parameters

`d`

  Specifies double precision value to break into a pair of unsigned integers.

## Description

`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.
