:00000,?>: as result of interval

[Beginner]

Hello,

thanks for your advice! In the CAS mode all went well.

What is a "non normalized" number? In what other situations could such a result appear on the screen?

Perhaps it would be helpful to give an explanation in the "help" menue if this output is typical for a certain set of mathematical tasks?

Or will this problem probably disappear again in a further update of the firmware?

Again: Thank you for your help!
