Bug with Integers

[nlj]

FWIW, on the 50g,

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)?
