Pipes to sum price

  transform(quantity: number, unitprice: number): any {

    if (isNaN(quantity) || quantity === null) return ''; // Handle non-numeric values

    if (isNaN(unitprice) || unitprice === null) return '';

    // Round the number to the specified decimal places

    // const roundedValue = Number(value.toFixed(decimalPlaces));

      const exitprice=quantity * unitprice;

        return exitprice

  }
