@Dhamu The code you have written is JavaScript. Before including jQuery, try to understand what jQuery is. – Exception Oct 10 '13 at 05:27

@Dhamu you don't use jQuery here. Anyway you should read about what `float` are and why the result you see is correct. – t.niese Oct 10 '13 at 05:36

Use toFixed() like
Total =Total.toFixed(1);
Or Simply,
Total = (parseFloat(subtotal)+parseFloat(tax)).toFixed(1);
