Name

| (bitwise OR)

Description

Compares each corresponding bit in the binary representation of the values. For each comparison two 1's yield 1, 1 and 0 yield 1, and two 0's yield 0. This is easy to see when we look at the binary representation of numbers

  11010110  // 214
| 01011100  // 92
  --------
  11011110  // 222

To see the binary representation of a number, use the binary() function with println().

Examples

  • int a = 205;   // In binary: 11001101
    int b = 45;    // In binary: 00101101
    int c = a | b; // In binary: 11101101
    println(c);    // Prints "237", the decimal equivalent to 11101101
    
  • 
    int a = 255 << 24; // Binary: 11111111000000000000000000000000
    int r = 204 << 16; // Binary: 00000000110011000000000000000000
    int g = 204 << 8;  // Binary  00000000000000001100110000000000
    int b = 51;        // Binary: 00000000000000000000000000110011
    // OR the values together:    11111111110011001100110000110011 
    color argb = a | r | g | b; 
    fill(argb); 
    rect(30, 20, 55, 55);
