CoffeeScript Math - pow()

---

Description

The pow() method accepts two numbers, a base and an exponent and this method returns the base to the exponent power, that is, base^exponent.

Syntax

Given below is the syntax of pow() method of JavaScript. We can use the same method in the CoffeeScript code.

Math.pow ( x )

Example

The following example demonstrates the usage of the pow() method in CoffeeScript. Save this code in a file with name math_pow.coffee.

value = Math.pow 7, 2
console.log "The value of pow(7,2) is : " + value 
         
value = Math.pow 3,9
console.log "The value of pow(3,9) is : " + value 

value = Math.pow 12,8
console.log "The value of pow(12,8) is : " + value 

value = Math.pow 125,0
console.log "The value of pow(125,0) is : " + value 

Open the command prompt and compile the .coffee file as shown below.

c:\> coffee -c math_pow.coffee

On compiling, it gives you the following JavaScript.

// Generated by CoffeeScript 1.10.0
(function() {
  var value;

  value = Math.pow(7, 2);

  console.log("The value of pow(7,2) is : " + value);

  value = Math.pow(3, 9);

  console.log("The value of pow(3,9) is : " + value);

  value = Math.pow(12, 8);

  console.log("The value of pow(12,8) is : " + value);

  value = Math.pow(125, 0);

  console.log("The value of pow(125,0) is : " + value);


}).call(this);

Now, open the command prompt again, and run the CoffeeScript file as shown below.

c:\> coffee math_pow.coffee

On executing, the CoffeeScript file produces the following output.

The value of pow(7,2) is : 49
The value of pow(3,9) is : 19683
The value of pow(12,8) is : 429981696
The value of pow(125,0) is : 1
