Are there any best practices for formatting floating point numbers in PHP to ensure accuracy and consistency?

When working with floating point numbers in PHP, it is important to format them properly to ensure accuracy and consistency. One common issue is the loss of precision when displaying floating point numbers, which can lead to unexpected results. To address this, you can use the number_format() function in PHP to format floating point numbers with a specified number of decimal places.

$number = 123.456789;
$formatted_number = number_format($number, 2); // Formats the number to 2 decimal places
echo $formatted_number; // Output: 123.46
