Name  & (bitwise AND) 


Examples  int a = 207; // In binary: 11001111 int b = 61; // In binary: 00111101 int c = a & b; // In binary: 00001101 println(c); // Prints "13", the decimal equivalent to 00001101 color argb = color(204, 204, 51, 255); // The sytax "& 0xFF" compares the binary // representation of the two values and // makes all but the last 8 bits into a 0. // "0xFF" is 00000000000000000000000011111111 int a = argb >> 24 & 0xFF; int r = argb >> 16 & 0xFF; int g = argb >> 8 & 0xFF; int b = argb & 0xFF; fill(r, g, b, a); rect(30, 20, 55, 55); 

Description  Compares each corresponding bit in the binary representation of the values. For each comparison two 1's yeild 1, 1 and 0 yeild 0, and two 0's yeild 0. This is easy to see when we look at the binary representation of numbers
11010110 // 214 & 01011100 // 92  01010100 // 84To see the binary representation of a number, use the binary() function with println().
