Random Numbers (en)

Random numbers are often used in programming, everywhere from encrypting data to generative design. Processing offers simple function to get a random number:

random([lower Limit],[upper Limit])

void setup()
{
  size(500,500);
  background(255);
  fill(255);
  stroke(0);
}
   
void draw()
{
  //fill(random(100,150),random(0,100),random(150,255));
  float size = random(10,100);
  ellipse(random(0,width),random(0,height),size,size);
}
