How can formatting issues with float values be avoided when dealing with arrays in PHP?

When dealing with arrays in PHP that contain float values, formatting issues can arise due to the inherent imprecision of floating-point numbers. To avoid this problem, you can use the number_format() function to format the float values to a specified number of decimal places. This ensures that the float values in the array are displayed accurately without any unexpected rounding errors.

$floatArray = [0.1, 0.2, 0.3, 0.4];

foreach ($floatArray as $float) {
    echo number_format($float, 2) . PHP_EOL;
}
