• num: This is a number of which the fractional part is to be found out.

Return Value: It returns a number with the fractional part of the given number.

Below example illustrates the fract() function in p5.js:

Example:

function setup() {
  createCanvas(600, 200);
  textSize(22);

  text("Move the slider to observe the effects"+
       " of the fract() function", 20, 30);

  sliderElem = createSlider(-5, 5, 0, 0.0001);
  sliderElem.position(20, 50);
}

function draw() {
  clear();
  text("Move the slider to observe the"+
       " effects of the fract() function", 20, 30);

  sliderVal = sliderElem.value();

  // Find the fractional part of the number
  fractionalVal = fract(sliderVal);

  text("The slider value is: " + sliderVal, 20, 100);
  text("The fractional value is: " + fractionalVal, 20, 120);
}
