Detailed Description

expression(s) evaluation based on a string.

The a2dEval module provides a class that allows you to incorporate mathematical expression evaluation into your programs, that can be changed at run time. For example, using the class you can evaluate such expressions as:

        1+1
        10 * (x=5)                 <== Assigns 5 to X first!
        ((1/3) * sin(45))^2
        X=50
        Y=100
        z=hypot(x,y)
    

You can extend Constants and Functions that can be used.
