Example

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

value = Math.abs(-1);
console.log "The absolute value of -1 is : " + value 
         
value = Math.abs(null);
console.log "The absolute value of null is : " + value 
         
value = Math.abs(20);
console.log "The absolute value of 20 is : " + value

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

c:\> coffee -c math_abs.coffee

On compiling, it gives you the following JavaScript.

(function() {
  var value;

  value = Math.abs(-1);

  console.log("The absolute value of -1 is : " + value);

  value = Math.abs(null);

  console.log("The absolute value of null is : " + value);

  value = Math.abs(20);

  console.log("The absolute value of 20 is : " + value);

}).call(this); 

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

c:\> coffee math_abs.coffee

On executing, the CoffeeScript file produces the following output.

The absolute value of -1 is : 1
The absolute value of null is : 0
