In this article we will learn few important math functions in javaScript
Math functions in JavaScript:
Part -2
This is the next part of
“Math functions in JavaScript” article. In our previous article we have learned
various Math function in JavaScript, in this article we will understand few
more of them.
random() function
random() function is
very useful to get random number in JavaScript. It generates random number from
0 to 1. This function might useful for various JavaScript game.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<script>
console.log("Random value is :- " + Math.random());
</script>
</body>
</html>
min() function
min() function is used to get minimum value among a set of
value. We can supply direct value or specify variable as argument of min()
function. Try to understand below example
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<script>
var c = 30;
console.log("Minimum value is :- " + Math.min(10,20,c));
</script>
</body>
</html>
Here is sample example
pow() function
pow() function is useful to get power of some number. In
this example we are calculating 10 to the power of 2. The first argument is base and second
argument is index.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<script>
console.log("10 to the power 2 is :- " + Math.pow(10,2));
</script>
</body>
</html>
Here is output.
sin() ,cos() and tan() function
In this example we calculate sin, cos and tan value of
certain number. Have a look on below example
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<script>
console.log("Sin of 10 is :- " + Math.sin(10));
console.log("cos of 10 is :- " + Math.cos(10));
console.log("Tan of 10 is :- " + Math.tan(10));
</script>
</body>
</html>
Here is sample output.
abs() function
This function is useful when we want to get absolute value
of a number. In this example we are passing a real number as argument of abs()
function.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<script>
console.log("Absolute value of 10.100 is :- " + Math.abs(10.100));
</script>
</body>
</html>
Conclusion:-
In this article we have seen few more math functions in
JavaScript. Hope you
have understood the concept.
