    Default Calculate formula which is in a String

    Hello People
    I was wondering if it is Possible to somehow get the result of a calculation I have in a String?
    For example at the end of my Code I get a String which contains

    "(3*2)+3"

    And as a result I want to get... well the result of that calculation. (In this example "9")

    Now do I have to split every single character out and calculate it like this? Or is there a more efficient way?
    Of course the Formula could be different every time.

    Thanks for your help and time

    Default Re: Calculate formula which is in a String

    I wrote a blog once for this forum that explains and implements a simple expression compiler and interpreter; (see the link on the right side of this reply).

    kind regards,

    Jos
