So i made a function that calculate the price by multiplication how many meters i put the problem is when ever i put decimal numbers it ignores it
heres my script
<script>
function getFillingPrice() {
cake_prices = document.getElementById('price').value;
filling_prices = document.getElementById('test2').value;
var t=parseInt(filling_prices);
var x=parseInt(cake_prices);
return t*x;
}
function calculateTotal() {
var total = getFillingPrice();
var totalEl = document.getElementById('totalPrice');
document.getElementById('test3').value =total + " دينار ";
totalEl.style.display = 'block';
}
</script>

Beside the parsing problem, you could use
an unary plus +
and
a default value for non parsable value, like letters or an empty string (falsy values) with a logical OR ||
.
cake_price = +document.getElementById('price').value || 0
// ^ unary plus for converting to numbner
// ^^^ default value for falsy values
Together
function getFillingPrice() {
var cake_price = +document.getElementById('price').value || 0,
filling_price = +document.getElementById('test2').value || 0;
return cake_price * filling_price;
}

You're converting the values to integers when you get them from the DOM.
Change this...
var t=parseInt(filling_prices);
var x=parseInt(cake_prices);
to this...
var t=parseFloat(filling_prices);
var x=parseFloat(cake_prices);
