Thanks for ur reply . The equation builder can be achieved this way. But if the query is complex it takes a long way ... like looking for the innermost brackets, aplying square roots , squares , * , / , + , - etc ..and more . So i was looking for some library class which can take an arithmetic equation and deliver its result .. but if this sort of thing is not available .. then i will have to develope it.
