Hi all experts ,Masters
I am developing a scientific calculator , in which i have to execute an expression.
I used QScriptEngine and QScriptValue classes .
It Works fine for simple arithmatics .
I have used Math.sin() , Math.cos() , Math.PI for executing the desired operations Math.pow(2,3) function for finding powers , but i want to use '^' operator instead of that function.
Is there any other class which will reduce my work.
I found QExpressionEvaluator , it is in a QBaseModule module .Please tell steps me how to use ExpressionEvaluator .
I am using Qt 4.4 and it does'nt have QExpressionEvaluator.
