a port of the Processing Visualization Language
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  // 84

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