Objects like simple values in expressions

[Big-Gremlin]

Is it possible to use objects like simple values?

Example:

export class CalcObj {
    value: number;
    filtered: boolean;

    constructor(value: number) {
        this.value = value;
    }
}

const scope = {
    objA: new CalcObj(3),
    objB: new CalcObj(2)
}

const result = math.eval('objA + objB', scope); 
# result = 5

Can a special function be used, such as toString () or something similar?

export class CalcObj {
    public value: number;
    public filtered: boolean;

    constructor(value: number) {
        this.value = value;
    }

   public toString(): string {
       return this.value
   }
}

It is possible to add support for a new data type and do calculations with it in the expression parser. You can find a small demo here:

is that what you mean?

This is a Question, rather than an issue. Moving.
