In the comments for what the HasErrors() function returns, it says: "True if the expression syntax is correct, otherwiser False". Isn't the opposite true? Does it not return True if there is an error, and False if everything is OK?

Recently I setup a new build server that uses VS 2017 for builds and executes the tests within VS.
Our old build server and all our dev machines all run the tests fine but this one new build server for some reason is throwing this exception during the build process on a few of our tests ...

NCalc.EvaluationException: Type 'System.Diagnostics.TraceEventCache' in assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.

Have you guys ever come across this?

Looking at the capabilities the only difference I could see was that the old build box used the previous version of VS (2015) and the new one uses 2017, both VS versions are Enterprise.

Other than that everything seems to be the same except for the OS as our old build box was a windows 10 box the new one is a server (windows 2016).

Maybe this is something to do with running the build process on a server?

Hello, I'm wondering whether this project is alive.
The issues are not being answered, pull requests are not discussed.
Any updates planned?

Thanks.

I randomly get this exception when calling Evaluate from the middleware of my ASP.Net Core web application. All I do is pass a string into the expression. I cannot think of any way that I can be affecting any collections in a non-concurrent way. Any suggestions?

NCalc.EvaluationException: Operations that change non-concurrent collections must have exclusive access.
A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct. at NCalc.Expression.Evaluate()

            var eap = new NCalc.Expression(expression);
            return eap.Evaluate();

Is there a way to make it detect divide by zero and integer overflow? 2/0 returns infinity and multiplying large numbers returns a negative number.

Asynchronous methods and EvaluationHandlers would be useful for working with databases and other long operations.
