random():
float x = random(1, 100);
rect(100, 100, w, 50); //A random float number between 1 and 100

int w = int(random(1, 100));
rect(100, 100, w, 50); //A random integer number between 1 and 100

constrain():
r = constrain(r, 0, 255);
g = constrain(g, 0, 255);
b = constrain(b, 0, 255); //Constrain all color values to between 0 and 255
