Evaluator

Hi,

this is a simple expression evaluator.
You can input a term like "1+1" or "(3**4=3^4)+log(100,10)-cos(2*Pi)*2"
and it will calculate it for you.
Supports simple operators ( + - * / ^ < > <> = ), brackets, variables and functions with any number of parameters.

Using the class in your code is very easy.
This example will print the first 10 powers of 2.

Code:

---

Dim clsEval As New Evaluator

clsEval.AddVariable "x", 0

If clsEval.Parse("2^x") Then
  For i = 0 To 9
      clsEval.VariableValue("x") = i
      Debug.Print clsEval.Evaluate()
  Next
Else
  MsgBox "Error while parsing!"
End If
