Understanding the Basic Math Functions in JavaScript

In this blog, we will learn the basic and most useful Math functions, available in JavaScript. These functions can be used for basic Math calculation.

<script>
    //Math.abs()
    alert(Math.abs(-100.24)); //Returns Absolute value (value without negative
    or positive sign) of numbers.
    Output will be 100.24

    //Math.ceil()
    alert(Math.ceil(100.24)); //Rounds a number upwards to the nearest integer.
    Output will be 101

    //Math.floor()
    alert(Math.floor(100.85)); //Rounds a number downwards to the nearest integer.
    Output will be 100

    //Math.max()
    alert(Math.max(80, 100, 15, 75)); //Return the number with the highest value
    from the set of numbers.Output will be 100

    //Math.min()
    alert(Math.min(80, 100, 15, 75)); //Return the number with the lowest value
    from the set of numbers.Output will be 15

    //Math.pow()
    alert(Math.pow(5, 3)); //Returns value of first number to the power
    of second number(5 to the power of 3).
    Output will be 125

    //Math.random()
    alert(Math.random()); //Returns a random number between 0 and 1.

    //Math.round()
    alert(Math.round(100.50)); //Rounds a number to nearest integer.
    Output will be 101

    //Math.sqrt()
    alert(Math.sqrt(25)); //Returns Square root of a number.
    Output will be 5
</script>
