[BUG] Integer manipulation tool broken in newer (v5447) Firmware?

[Stefan]

Ok, thanks to the help of both of you I got it working now. My errors where that
1. I thought that the Prime would automatically convert the number to an integer as soon as I would press the button for the integer manipulation tool
2. I was in the CAS environment. (Although I don't see a reason why the tool should not work in the CAS envoronment.)

Thank you.
