Apporach 2: Using Math.atan()
Javascript Math.atan( ) method is used to return the arctangent of a number in radians. The Math.atan() method returns a numeric value between -pi/2 and pi/2 radians.
Syntax:
Math.atan(value)
Example: In this example we are using the above-explained method.
Javascript
const val = 4 * (Math.atan(1)); console.log("value of π is :", val); |
Output
value of π is : 3.141592653589793
