PDO Btc number addition error :     $score = $_GET['score'];
    $ht = $ayarcek['total'];
    $total = $ht+$score;``
    echo $total;

    Result: 6.0E-8


I want to summarize the numbers 1.000000 + 0 or 1.000000 + 1.000000 but when I do the collection I get the above result. Where could I have done wrong? (BTC)
