7^23 MOD 143 ==> 23

(r8151 Default settings)

Perhaps Helge is using an older version, and I get this in Home and CAS,I think hardware does not matter here, this is the result I get from real calc, Pc and Android.
Thank you

Well, in Home this result is normal: I get 23 also on my 48GX. You are limited by the number of significant digits. You cannot fully express 7^23 with 12 significant digits.
On my 41CX I get 66 and on the WP 34S I get 84.

In CAS I get 2, as Helge, both on the real and the virtual calculators and I have the latest Revision: 8151.

Juste one question: are you entering MOD in upper case in CAS ?
