In PHP, how to print a number with 2 decimals, but only if there are decimals already?

Question

I have a basic index.php page with some variables that I want to print in several places - here are the variables:

Answer 1

What about something like this :

$value = 15.2; // The value you want to print

$has_decimal = $value != intval($value);
if ($has_decimal) {
    echo number_format($value, 2);
}
else {
    echo $value;
}

Notes :

• You can use number_format() to format value to two decimals
• And if the value is an integer, just display it.
