codeigniter round off function

To round off a number in CodeIgniter, you can use the round() function provided by PHP, as CodeIgniter is built on top of PHP. The round() function allows you to round a number to a specified number of decimal places. Here are the steps to use the round() function in CodeIgniter:

1. Load the helper: First, you need to load the helper that contains the round() function. In CodeIgniter, you can load a helper using the helper() function. For example, to load the number_helper helper that contains the round() function, you can use the following code:

$this->load->helper('number');

1. Use the round() function: Once the helper is loaded, you can use the round() function to round off a number. The round() function takes two parameters: the number you want to round and the number of decimal places to round to. Here's an example of how to use the round() function to round off a number to 2 decimal places:

$number = 3.14159;
$rounded = round($number, 2);

In this example, the variable $number contains the number 3.14159, and the variable $rounded will contain the rounded value, which will be 3.14.

That's it! You have successfully used the round() function in CodeIgniter to round off a number to a specified number of decimal places. Remember to load the helper that contains the round() function before using it.
