JavaScript Math PI Property Last Updated : 15 Jul, 2024 Comments Improve Suggest changes Like Article Like Report 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.PIReturn values:It simply returns the value of PI i.e, ΠExample 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: 3.141592653589793Example 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: 3.141592653589793Example 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 functionExample 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: 78.53981633974483We have a complete list of Javascript Math Objects methods, to check those please go through this Javascript Math Object Complete reference article.Supported Browsers: Chrome 51 Edge 15 Firefox 54 Safari 10 Opera 38 Comment More infoAdvertise with us Next Article JavaScript Math SQRT1_2 Property K Kanchan_Ray Follow Improve Article Tags : JavaScript Web Technologies javascript-math JavaScript-Properties Similar Reads JavaScript Math E Property The Math.E is a property in JavaScript that simply returns the value of Euler's Number, which is nothing but just has a base of the natural logarithm.
