Calculator.NET - Calculator that evaluates math expressions

I'd like to announce the release of a little project I've been working on.  I call it Calculator.NET.  I started this project for a couple reasons.  First, I was annoyed that Windows Vista doesn't come with a better calculator.  Windows XP has Power Calculator, but that doesn't work on Vista.  Next, I was reading a blog about DynCalc by Bart De Smet on how to do mathematical calculations. That gave me the starting point on how to create Calculator.NET. 

As part of the project, I created a MathExpressions library that does the bulk of work.  The library supports math expressions, functions unit conversion and variables. Below are some examples of using the library directly.

MathEvaluator eval = new MathEvaluator();
//basic math
double result = eval.Evaluate("(2 + 1) * (1 + 2)");
//calling a function
result = eval.Evaluate("sqrt(4)");
//evaluate trigonometric
result = eval.Evaluate("cos(pi * 45 / 180.0)");
//convert inches to feet
result = eval.Evaluate("12 [in->ft]");
//use variable
result = eval.Evaluate("answer * 10");
//add variable
eval.Variables.Add("x", 10);
result = eval.Evaluate("x * 10");
