JavaScript Math PI Property (original) (raw)

Last Updated : 15 Jul, 2024

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

**Example 1: 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 2: 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 3: 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 4: 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
