JavaScript CEIL

by

The JavaScript CEIL function is one of the JavaScript Math function and it is used to return the smallest integer value which is greater than or equal to the specified expression or an individual number. In this article we will show you, How to use CEIL() function in JavaScript Programming language with example.

Syntax of a JavaScript CEIL Function

The basic syntax of the JavaScript CEIL Function is as shown below:

Math.ceil(number);

Number: It can be a number or a valid numerical expression on which you want to perform ceiling.

  • If the number argument is positive or negative number, ceil() function will return the ceiling value.
  • If the number argument is not a number, ceil() function will return NaN.
  • If the number argument is Null, ceil() function will return Zero.

JavaScript CEIL Function Example

The JavaScript CEIL Function allows you to find the smallest integer value which is greater than or equal to the numeric values. In this example, We are going to find the ceiling values of different data types and display the output

JAVASCRIPT CODE

<!DOCTYPE html>
<html>
<head>
    <title> JavaScript CEIL Function </title>
</head>
<body>
  <h1> JavaScript CEIL Function </h1>
  <p id = "Pos"></p>
  <p id = "Neg"></p>
  <p id = "Dec"></p>
  <p id = "Dec1"></p>
  <p id = "Neg_Dec"></p>
  <p id = "Neg_Dec1"></p>
  <p id = "Str"></p>
  <p id = "Exp"></p>
  <p id = "Null"></p>
  <script>
    document.getElementById("Pos").innerHTML = Math.ceil(20);
    document.getElementById("Neg").innerHTML = Math.ceil(-20);
    document.getElementById("Dec").innerHTML = Math.ceil(10.05);
    document.getElementById("Dec1").innerHTML = Math.ceil(10.95);
    document.getElementById("Neg_Dec").innerHTML = Math.ceil(-6.05);
    document.getElementById("Neg_Dec1").innerHTML = Math.ceil(-6.95);
    document.getElementById("Str").innerHTML = Math.ceil("JavaScript");
    document.getElementById("Null").innerHTML = Math.ceil(null);
  </script>
</body>
</html>

ANALYSIS

  1. First two statements, We used the CEIL() Function directly on both the Positive integer and negative integer.
  2. Next four statements, We used the CEIL() Function on both the Positive and negative Decimal values.
  3. Next statement, We tried CEIL() Function on String value. As we said before, this will return NaN (Not a Number) as output
  4. Last, We tried CEIL() Function on Null value and it return Zero as output

OUTPUT

JavaScript CEIL Function
