Primitive types of Gray codes introduced by Frank Gray

Quick start

The package can be installed with the Julia package manager. From the Julia REPL, type ] to enter the Pkg REPL mode and run:

Usage

To use Gray code to represent integer:

julia> using GrayCode

julia> Gray8(5)
Gray8(5)

julia> Gray16(5)
Gray16(5)

julia> Gray32(5)
Gray32(5)

julia> Gray64(5)
Gray64(5)

julia> Gray128(5)
Gray128(5)

julia> Gray(5)
Gray64(5)

To convert Gray code to 2's complement representation:

julia> typeof(Integer(Gray8(5)))
UInt8

julia> Integer(Gray8(5))
0x05

Bit pattern of Gray codes

julia> @. bitstring(Gray8(0:7))
8-element Vector{String}:
 "00000000"
 "00000001"
 "00000011"
 "00000010"
 "00000110"
 "00000111"
 "00000101"
 "00000100"
