i have a string like that
str = "4975 + 10 * (LOG(250.6)) - 321.2"
i want to compute the result of this operation. Is there any sort way to do that?
// my operation just includes some of operators (,), +, -, *, / , ., 0-9, LOG
// '.' is used for double number
I believe this is what you are looking for.
Use this library will help you to perform math operations in string format
Add this package
Install-Package DynamicExpresso.Core
code example
public static void Main(string[] args)
{
var interpreter = new Interpreter();
var result = interpreter.Eval("4975 + 10 * (LOG(250.6)) - 321.2".Replace("LOG", "Math.Log"));
Console.WriteLine("result=> " + result);
Console.ReadKey();
}
result=> 4709.03858042462

Also answered here:
I do not have a .net box lying around so I cannot confirm whether it can do log
or not, but I have used it for long algebric expressions.
Basically this is how it goes:
DataTable dt = new DataTable();
var ans = dt.compute("5 + (7 - 9) / 3");
