Determinant example in help fails in CAS

[robmio]

Hi, grsbanks. In fact they are both built by the same codebase (at least I suppose that's the case). However, why can't the HP PRIME G2 calculator ("physical" version with firmware 20200121) calculate the following operation (see post: "Error with exp function and imaginary numbers")?

cos(1e49) -> 0.70354916584 (virtual calculator)

cos(-1e49) -> -Inf (HP PRIME G2 "hardware", firmware 20200121).

I cordially greet you, Roberto.
