Hello, thanks a lot for your library!
I would like to reference it as a NUGet Package but, looking at NUGet Gallery, I've only found this package: https://www.nuget.org/packages/CalcEngine.Core
It is a porting for .NET of your CodeProject article, but I'm still using .NET Framework.
Can I help in some way, maybe creating the package and publishing it on the gallery? It's a new task for me, but I'll try to make it.
Please let me know.

Use Math.Truncate() instead of the casting (double)(int)((double)p[0]);

Hello,

Thank you for this library. I'm starting a few tests. So I included calcEngine project into my test solution but I have an exception message when I instantiate the calcEngine which is due to the tests being performed.

I don't know if it has an impact anywhere else anyway I thought it was worth mentioning.
My system is configured in french so In debug, there is an exception during tests because 1 234,00 is returned when 1,234.00 is expected.

Thank you

Hello Bernardo,

Thank you for your quick answer. I'm trying to replace another lib with yours in my project but I'm struggling with minor issues. For instance this if(5>0,3,2) returns 3 but I get a syntax error with this if(5>0 and 5>2,3,2). I tried using & also.

Also how can I have variables with white spaces. If I use [x y] I get an exception, same if I try "x y".

I guess these are not issues but improper use that's why I was wondering if there was any documentation that could help me.

If you ever come to release a new version in the future, may I suggest the use of a constants file for the function names and error messages to help with the localization issues.

Thanks a lot for your time and effort as your library is really helping.

Regards
Amar

First thank you very much for this library and the article. And thank you for opening it for everybody, I appreciate it.
I tried to run it as a CLR Component in SQL Server. (That would allow me to calculate formula directly in SQL-Queries). In order to register this library in SQL Server with permission set "safe", I had to mark static variables as readonly in two places:

• MathTrig.cs, Row 216: "static readonly Random _rnd = new Random();
• Expression.cs, Row 27: static readonly CultureInfo _ci = CultureInfo.InvariantCulture;

If you could adopt those changes, that would allow to use your library as a "safe" under SQL Server without manual changes.

I see that the original Code Project article for this project lists the COPL as the license under this code is released; is that still in effect? If not, is it possible to specify a license in this GitHub project (the MIT license seems the closest, but obviously that's your call).
