Examples
let x = round(3.7);
text(x, width / 2, height / 2);let x = round(12.782383, 2);
text(x, width / 2, height / 2);function draw() {
background(200);
//map, mouseX between 0 and 5.
let ax = map(mouseX, 0, 100, 0, 5);
let ay = 66;
// Round the mapped number.
let bx = round(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);
