Use number_format function in PHP.

number_format ( float $number [, int $decimals = 0 ] ) : string
For more information see here

$yourNumber = 1235.343;

echo number_format ($yourNumber, 2);

// Will output 1,235.34 (with two decimals, specified in number_format as second paramter.

Edit: Max / Min functions return mixed value. Make sure its float and then pass it to number_format. It will returns you the string.
