In this tutorial will give you an example of PHP format number with 2 decimals. You will learn PHP number with 2 decimals. Rounding numbers to a specific decimal place is a common use in programming.
We will give you more method to converting float to 2 decimal places. So, let us see in detail an example.
- Using number_function() function
- Using round() function
- Using sprintf() function
