When calculating an expression, an error is reported if the expression has [] in it.

Error in calculation of (-CWPT_007_P)+[1-(-0.3)]: Expression expected (at index 14).

Can you post some actual text code to reproduce the problem?

You're using brackets as parenthesis, which is not supported:

(-23)+[1-(-0.3)]

should be

(-23)+(1-(-0.3))

(-23)+(1-(-0.3))

I can understand using parentheses to replace square brackets, e.g. (-23)+(1-(-0.3)), but there are square bracketed expressions in mathematical logic, which can be confusing for the user

Sample code for example:

static void Main(string[] args)
{
    var interpreter = new Interpreter();
    var parameters = new[] {
        new Parameter("CWPT_007_P", 23),
        new Parameter("CWPT_007_S", -0.3),
    };
    var value= interpreter.Eval("(-CWPT_007_P)+[1-(CWPT_007_S+5)]", parameters);  
    Console.WriteLine($"value: {value}");
}

I agree with you @landonzeng , but DynamicExpresso is not a math interpreter, the goal is to create a C# interpreter.
If you realy want to use DynamicExpresso for math maybe you can try to do some preprocessing first, for example replacing [ ] with ( ). But I suspect that it is not the right tool to be honest.

Yes, that's what I was thinking, I had to replace [] with () if I wanted to fulfil a customer request and that was it.
