Determinant example in help fails in CAS

[robmio]

Hi, I used radians. However, since the cosine of an angle can vary only from -1 to +1, regardless of the angular units, the operation: cos(10e49) cannot give a result = + inf.
The error appears only in the HP PRIME G2 (hardware version, last firmware: January 21, 2020, CAS view).
Hopefully HP will fix it quickly, along with other bugs. This error, in fact, prevents the numerical calculation of some integrals not only in CAS view, but also in HOME view:

romberg(exp(-(z)*sinh(t)-n*t),t,0,∞)

with "z" as complex number.
