This article mainly introduces "what is the function of finding the root in javascript". In the daily operation, I believe that many people have doubts about what the function of finding the root in javascript is. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubt of "what is the function of finding the root in javascript?" Next, please follow the editor to study!

The function of finding the root in javascript: 1, the sqrt () function, the syntax "Math.sqrt (x)", can calculate the square root of the number x; 2, the pow () function, the syntax "Math.pow (x, (1max y))", can calculate the y-th root of the number x.

The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.

Javascript seeking the root

1. Use the sqrt () function

The sqrt () method returns the square root of the number.

Syntax:

Math.sqrt (x)

Example:

Var Xerox 9position console.log (Math.sqrt (x))

Output result:

2. Use the pow () function

Math.pow (XBI y) can be the power of x to the y. When y is a decimal (1 stroke y), it can be used to calculate the root sign.

Function f (Xrem y) {yard1gray y; console.log (Math.pow (XJO y));} f (4J2); f (125J3); f (81Pol 4)

At this point, the study of "what is the function of finding the root in javascript" is over. I hope to be able to solve your doubts.
