| 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;

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(). |
