Bug with Integers

7 ENTER 23 Y^X 143 MOD ==> 2
'7 Y^X 23 MOD 143' ENTER EVAL ==> 2

but

'7 Y^X 23 MOD 143' ENTER ->NUM ==> 23.

Note the decimal point.

Does the Prime not have an option to always show a decimal point on an floating point value? Otherwise how do you know if you're looking at a (precise) integral value or an approximation (potentially with rounding error or overflow)?

I haven't tried that with approx mode on on the 49G+, in exact mode this calc provided the awaited 2, interesting that approx mode delivers the 23 like the prime does. On the prime the problem seems to lie deeper in the system, both exact and approx with the CAS-order (mod(...)) deliver 23, only the (non-CAS)-command a MOD is correct, this must be manually entered and display with both possibilities is the same: 7^23 MOD 143, manually entered provides 2, mod chosen from catalog: 23. So I really am annoyed.
THX for your ideas
