if(isset($_POST['decimal'])) {
$decimal = $_POST['decimal'];
$original = $_POST['decimal'];
$binary='';
if (preg_match('/[^0-9]/',$decimal)) {
die("maaf. Inputan Anda Salah. .");
}
else {
while ($decimal > 0) {
if ($decimal%2 == 0){
$binary .=0;
$decimal /= 2;
}
else{
$binary.= 1;
$decimal = ($decimal/2)-0.5;
}
}
$result = strrev($binary);
echo "Bilangan $original (desimal) dalam biner adalah $result.
<a href='Konversi_Dec_to_Biner.php'>Back</a> to the script";
