CoffeeScript Math - floor()

Description

The floor() method accepts a number and returns its floor value.

Syntax

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

Math.floor ( x )

Example

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

value = Math.floor 10.3
console.log "The floor value of 10.3 is : " + value 
         
value = Math.floor 30.9
console.log "The floor value of 30.9 is : " + value 
         
value = Math.floor -2.2
console.log "The floor value of -2.2 is : " + value 

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

c:\> coffee -c math_floor.coffee

On compiling, it gives you the following JavaScript.

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

  value = Math.floor(10.3);

  console.log("The floor value of 10.3 is : " + value);

  value = Math.floor(30.9);

  console.log("The floor value of 30.9 is : " + value);

  value = Math.floor(-2.2);

  console.log("The floor value of -2.2 is : " + value);


}).call(this);

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

c:\> coffee math_floor.coffee

On executing, the CoffeeScript file produces the following output.

The floor value of 10.3 is : 10
The floor value of 30.9 is : 30
The floor value of -2.2 is : -3
