Strange behavior of HP prime pro app

[rawi]

Hi roadrunner,

thank you very much.

I tried your code and unfortunately it did not work with my version of the Prime Pro PC software. Now it did not stop and closed the app but it went on and on. After 20 minutes I terminated the process.

I tried as well your code on a Prime calculator. There it worked perfect and gave the right results in about 5 seconds.

I tried in the app with a debug. It was again the line with the first double integral that caused the problem. When I replaced that line with a simple 0.5 ▶ FL; it was the second line with the double integral that cased the same problem. It seems to me that the app has a problem with double integrals the calculator does not have.

Thanks again and best regards

Raimund
