Four years since the last post about this matter, I have the same problem. I need a way to evaluate a numeric expression write in a string (i.e, "2+2"). There was some conclusion about? I searched in the forge and found only one component (Evaluator), but generate an error when the extension is published.
Can someone help me?
NCALC worked just fine for me.
Thanks for your attention, How can I get the NCALC ?
And then use Integrations studio to create Actions
I created a simple wrapper around it, plus fixed the decimal/double/single stuff (see the NCalc website). You can find it here. Since we are on P10, it's P10 only, so I hope you're on P10 :).
Thank you very much by your attention.
But the problem is that I am using the Outsystems Cloud Personel Environment, and the version is 126.96.36.199. It doesn't installed because there was version conflict. Is there a version 9 to your component?
I was afraid of that :). Do you need version 9.1? Because you can request an upgrade to 10. I can see if I can create a v9 one, but it'll take some time.
Can I ask the version 10 to a free outsystems cloud personel environment?
As far as I know, yes. My cloud environment is also v10.
Thanks Kilian, I will ask a new version!!
You can follow these instructions: https://success.outsystems.com/Support/Personal_Environment/Upgrade_a_personal_environment_to_the_latest_version
I followed your recommendations, and my environment was already upgraded to version 10. Then, I installed your MathExpr component, and it works fine. I'm writing a applicative to industrial segment, and you gave me a GREAT help. Thank you very very very much by your attention.
Great to hear it worked. If you like, please rate the MathExprEval component, since you're the first one to use it :).
