How to avoid removing the last 0 of a floating number in the console?

March 11, 2022

Here is my code:

protected function roudUp(float $amount) : float {
    $fraction = self::ROUNDING_PRECISION > 0 ? self::ROUNDING_PRECISION : 0; 
    $mult = pow(10, $fraction);
    $roundedUp = ceil($amount * $mult) / $mult;
    return number_format($roundedUp, 2);
}

It works properly and returns always two decimal places like 1.60. But it converts to 1.6 in the console. See:

The expected result is:

How can I avoid that?

>Solution :

number_format() returns a string. The function must also return a string and not a float!

function roudUp(float $amount) : string {
    $fraction = 2; 
    $mult = pow(10, $fraction);
    $roundedUp = ceil($amount * $mult) / $mult;
    return number_format($roundedUp, 2);
}

echo roudUp(1.6);  //1.60
