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, baseexponent.

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
