How can developers optimize their code to minimize the impact of floating point precision errors in PHP?

Floating point precision errors in PHP can be minimized by using functions like round(), number_format(), or BCMath functions for arithmetic operations. Additionally, developers can use the ini_set() function to adjust the precision settings in PHP to a higher value. 

// Adjusting the precision settings in PHP
ini_set('precision', 14);

// Using round() function to minimize floating point precision errors
$number = 1.23456789;
$rounded_number = round($number, 2);
echo $rounded_number;
