Hello everyone. I discovered that the "HP PRIME" calculator can calculate the incomplete gamma function. For example:

"approx (Gamma (2,2))"

returns: 0.40600584971 (I checked the result with "Mathematica 12.0" by Wolfram).

However, the command:

"approx (Gamma (2,inf))"

does not directly return zero. Can you tell me why?
