Rounding up the prices to remove unwanted decimals - PHP

Question

I'm trying to round up the prices to remove the unwanted decimals in the sum of all the prices.Below is the screenshot for example,

So I need to adjust the prices to remove .2 decimal from the total.I tried below solution, but its only working for one set of prices not for other.

 <?php

$values = [436.4,207.3,87.3,218.2,196.4,54.6];


$final_array = $val_array = []; $sum =  0;

foreach($values as $v){

    $sum += roundValue($v, 5);
    $val_array[] = roundValue($v, 5);
}


function roundValue($number, $denominator = 1)
    {
        $x = $number * $denominator;
        $x = floor($x);
        $x = $x / $denominator;
        return $x;
    }


$final_array[] = ['sum' => $sum, 'rates' => $val_array];

var_dump($final_array);

?>

Please check this running example for first set of prices: first

Please check this running example for second set of prices: Second

and even tried with all these solutions below, nothing works for me:

round($number + 0.01) - 0.01;
round($number + 0.05) - 0.05;
floor($number*100)/100;

Any suggestions please?

Answer 1

What you're doing is juggling types.

Notice, that number_format returns string. You are adding that string to integer (or float later), so php is implicitly casting that string to int/float.

What you want to do (probably) is to make your computations on floats/integers and at the end, when you'd like to display it - use number_format .

I would advise to do some reading on types.
This will be a good start.
