I recently realised that "^" is not a Processing or Java operator.

So 2^5 must be computed using int(pow(2,5)), giving 32 as result.

Yet it is possible to use 2^5, without compiler error, but we get strange results.

 

The following code:

 

  for (int a=0; a<=10; a++) {
    print(" "+a+"^0..24: ");
    for (int n=0; n<=24; n++) {
      print((a^n)+" ");
    }
    println();
  }

gives this output:

 

  0^0..24:  0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
  1^0..24:  1 0 3 2 5 4 7 6 9 8 11 10 13 12 15 14 17 16 19 18 21 20 23 22 25
  2^0..24:  2 3 0 1 6 7 4 5 10 11 8 9 14 15 12 13 18 19 16 17 22 23 20 21 26
  3^0..24:  3 2 1 0 7 6 5 4 11 10 9 8 15 14 13 12 19 18 17 16 23 22 21 20 27
  4^0..24:  4 5 6 7 0 1 2 3 12 13 14 15 8 9 10 11 20 21 22 23 16 17 18 19 28
  5^0..24:  5 4 7 6 1 0 3 2 13 12 15 14 9 8 11 10 21 20 23 22 17 16 19 18 29
  6^0..24:  6 7 4 5 2 3 0 1 14 15 12 13 10 11 8 9 22 23 20 21 18 19 16 17 30
  7^0..24:  7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8 23 22 21 20 19 18 17 16 31
  8^0..24:  8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 24 25 26 27 28 29 30 31 16
  9^0..24:  9 8 11 10 13 12 15 14 1 0 3 2 5 4 7 6 25 24 27 26 29 28 31 30 17
 10^0..24: 10 11 8 9 14 15 12 13 2 3 0 1 6 7 4 5 26 27 24 25 30 31 28 29 18

I am just curious to know what "^" actually does.
