Are there built-in functions in PHP for handling exponential notation?

PHP provides built-in functions for handling exponential notation, such as number_format() or sprintf(). These functions can be used to format numbers in scientific notation or exponential notation with a specified number of decimal places. By using these functions, you can easily convert numbers to or from exponential notation in PHP.

// Example of using number_format() to format a number in exponential notation
$number = 1.2345e6;
$formatted_number = number_format($number, 2, '.', ''); // Output: 1,234,500.00
echo $formatted_number;
