The Math.PI is a property in JavaScript that is simply used to find the value of Pi i.e, in symbolic form Π which is nothing but it is the ratio of the circumference of a circle to its diameter, whose value is approximately 3.141. It is mainly used in mathematics problems.
Syntax:
Math.PI
Return values: It simply returns the value of PI i.e, Π
Below is an example of the Math PI Property.
Example: Here simply the value of PI is printed in the console.
Javascript
// Here value of Math.PI is printed.console.log(Math.PI); |
Output:
3.141592653589793
Example: The value of PI i.e, Π can be printed in the form of a function as shown below.
Javascript
// function is being called.function get_Value_of_PI() { return Math.PI;}// function is calling.console.log(get_Value_of_PI()); |
Output:
3.141592653589793
Example: Here we consider Math.PI is a function but in actuality, it is a property which is why the error as output is being shown.
Javascript
// Here we consider Math.PI as a function but// in actual it is a property that is why error// as output is being shown.console.log(Math.PI(12)); |
Output:
Error: Math.PI is not a function
Example: Whenever we need to find the value of anything related to PI that time we take the help of this property. In mathematics, it needed a lot. Here we are going to find the value of the area of a circle with the given value of its radius.
Javascript
// function is being called with radius 5 as a parameter.function area_of_circle(radius_of_the_circle) { return Math.PI * radius_of_the_circle * radius_of_the_circle;}// Here area of the circle is 5 unit.console.log(area_of_circle(5)); |
Output:
78.53981633974483
