      float r = random(50);
      stroke(r*5);
      line(50, i, 50+r, i);
    }
    for(int i=0; i<100; i++) {
      float r = random(-50, 50);

Description |  | Generates random numbers. Each time the random() function is called, it returns an unexpected value within the specified range. If one parameter is passed to the function it will return a float between zero and the value of the parameter. The function call random(5) returns values between 0 and 5. If two parameters are passed, it will return a float with a value between the the parameters. The function call random(-5, 10.2) returns values between -5 and 10.2. To convert a floating-point random number to an integer, use the int() function.
Syntax |  |

    random(value1, value2);
