>=20

You are doing the operation with ints! If you divide 994 by 1000 you will=
=20
get 0.994  .... now try to cast that to (int) and see what you get, you=20
will get zero, because that=B4s the way computers truncate!

You should then do like this:

 X =3D (float)a / (float)b  // and X MUST be a float or double=20

Hope it helped!  :)
