ror

ror(B::BitArray{1}, i::Integer) -> BitArray{1}

Performs a right rotation operation.

Examples

In the Julia programming language, the function ror(B::BitArray{1}, i::Integer)

Performs a right rotation operation on a BitArray and returns the modified BitArray.

julia> ror(bitstring(0b1100), 2)
0b0011

Provide common examples of its use:

1. Right rotate a binary number:

   julia> ror(bitstring(0b1010), 1)
   0b0101

   This example performs a right rotation of the binary number 0b1010 by 1 position.

2. Rotate a bit array:

   julia> bits = BitArray([true, false, true, false]);
   julia> ror(bits, 2)
   4-element BitArray{1}:
   0
   1
   0
   1

   It performs a right rotation of the bit array bits by 2 positions.

3. Rotate a bit array with negative index:

   julia> bits = BitArray([true, false, true, false]);
   julia> ror(bits, -1)
   4-element BitArray{1}:
   1
   0
   1
   0

   It performs a right rotation of the bit array bits by 1 position in the opposite direction.

Common mistake example:

julia> ror(bitstring(0b1100), -2)
ERROR: MethodError: no method matching ror(::String, ::Int64)

In this example, the input argument B is passed as a string (bitstring) instead of a BitArray. Make sure to provide a BitArray as the first argument to the ror function.
