Ask the user an expression which states the relationship between your variables, or declares logical properties and constraints: with this component you will be able to calculate the expression's result according to the user's formula or decide whether a user's constraint is verified. Give to the user full freedom: ask him a symbolic expression instead of letting him choose between predefined calculation algorithms. Of course you can check the expression's correctness and warn the user with appropriate messages.

An expression tree analyzer window can be displayed to the user, to let him see whether the expression has been correctly inserted.

A full set of operators and predefined function is available, together with the ability to define named variables.

Precision Expression Evaluator was written entirely in C++ and is composed of strongly speed and size-optimized code. The only required libraries are the MFC and MSVCRT DLL that are shipped with every version of Microsoft Windows. You do not need any additional libraries.

Expression Evaluator is only 60 k in size This means that it is very fastly loaded into your application and it does not significantly increase your final application size.
