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 00001101color 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 // 84


To see the binary representation of a number, use the binary() function with println(). Syntax value & value2 Parameters value1 int, char, byte value2 int, char, byte Usage Web & Application Related | (bitwise OR)binary()

Processing was initiated by Ben Fry and Casey Reas. It is developed by a small team of volunteers.
