Static p5_sys::global::sq

pub static sq: SqInternalType

Squares a number (multiplies a number by itself). The result is always a positive number, as multiplying two negative numbers always yields a positive result. For example, -1 * -1 = 1.

Examples

function draw() {
  background(200);
  let eSize = 7;
  let x1 = map(mouseX, 0, width, 0, 10);
  let y1 = 80;
  let x2 = sq(x1);
  let y2 = 20;

  // Draw the non-squared.
  line(0, y1, width, y1);
  ellipse(x1, y1, eSize, eSize);

  // Draw the squared.
  line(0, y2, width, y2);
  ellipse(x2, y2, eSize, eSize);

  // Draw dividing line.
  stroke(100);
  line(0, height / 2, width, height / 2);

  // Draw text.
  let spacing = 15;
  noStroke();
  fill(0);
  text('x = ' + x1, 0, y1 + spacing);
  text('sq(x) = ' + x2, 0, y2 + spacing);
}

Parameters

n number to square
