  background(200);
  //map, mouseX between 0 and 5.
  let ax = map(mouseX, 0, 100, 0, 5);
  let ay = 66;

  //Get the floor of the mapped number.
  let bx = floor(map(mouseX, 0, 100, 0, 5));
  let by = 33;

  // Multiply the mapped numbers by 20 to more easily
  // see the changes.
  stroke(0);
  fill(0);
  line(0, ay, ax * 20, ay);
  line(0, by, bx * 20, by);

  // Reformat the float returned by map and draw it.
  noStroke();
  text(nfc(ax, 2), ax, ay - 5);
  text(nfc(bx, 1), bx, by - 5);
}

Parameters

n number to round down
