Error with exp function and imaginary numbers

[robmio]

I have encountered an error, which perhaps detects a bug in HP PRIME G2 (hardware). For example, if I do this calculation with the virtual calculator: "exp (-10^49-10^49*i)", I rightly get zero. If, however, I perform the same operation with my HP PRIME G2 (i.e. hardware version with firmware 20200121), an error is displayed: +Inf. Maybe this depends on the fact that, for my G2 calculator, in "CAS" the operation "exp (-10^49-10^49*i)" is interpreted as "exp (+/- Inf)", which for the calculator corresponds to an undefined value. Is there anyone who, having an HP PRIME G2, can check if the problem is common or depends only on my calculator?

Thanks a lot, Roberto Mioni
