How to use Round, Random, Min and Max in JavaSript
468x60
Round, Random, Min and Max are the methods used in math object in JavaSript. Math object allows you to perform common mathematical tasks. The math object includes several mathematical values and functions. Yo do not need to define the math object before using it. In this post I am describing How to use Round, Random, Min and Max in JavaSript.
Using round() method in math object, you can round the given numbers as given below.
<script>
document.write(Math.round(0.60) +"<br/>");
document.write(Math.round(0.40) +"<br/>");
document.write(Math.round(0.49) +"<br/>");
document.write(Math.round(-3.69) +"<br/>");
document.write(Math.round(-6.10) +"<br/>");
</script>
You can use the random() method in math object,you can return a random number between 0 and 1 as given below.
<script>
document.write(Math.random());
</script>
Using max() method in math object, you can return the number with the highest value of two specified numbers as the following.
<script>
document.write(Math.max(9,3) +"<br/>");
document.write(Math.max(-5,7) +"<br/>");
document.write(Math.max(10,21) +"<br/>");
document.write(Math.max(-5,-9) +"<br/>");
document.write(Math.max(6.12,7.98) +"<br/>");
</script>
Using min() method in math object, you can return the number with the highest value of two specified numbers as the following.
<script>
document.write(Math.min(9,3) +"<br/>");
document.write(Math.min(-5,7) +"<br/>");
document.write(Math.min(10,21) +"<br/>");
document.write(Math.min(-5,-9) +"<br/>");
document.write(Math.min(6.12,7.98) +"<br/>");
</script>
There are also other more methods on JavaScript math object to perform common mathematical tasks which are listed below along with their description. You can use them as the methods given above.
