I have a complex problem, I am getting formulas form the database and I need to evaluate them. I choose to convert them to post fix...and evaluate them the problem is that.. my formulas are like
roundoff(vd,2);
udV=lookup(uv*dse,erd);
ude=if(er>es)?sr:ss;
Can anyone find a solution for these type of conversions and evaluations...
No, not without some more clarification from you. Perhaps you could tell us what sort of technology you are using and what some, at least, of your functions mean. As it stands I recommend that you use Mathematica because it's probably powerful enough to tackle this type of problem. If you don't have access to Mathematica, perhaps you could hook in to Wolfram Alpha for evaluations.
