THANK YOU!
mXparser provides a rich collection of built-in math functions, math expressions, and math symbols. Familiarize yourself with the scope and the syntax. Math collection internal help is also available directly from the software – see the tutorial and the API documentation for all the details. The math collection library is available at runtime and is fully and identically supported by the Java (including Kotlin, Android), C# (all .NET) and C++ versions.
