Re: HP Prime emulator: Gamma function Message #3 Posted by Gerson W. Barbosa on 21 Aug 2013, 3:03 p.m., in response to message #2 by Tim Wessman
On the HP49G+ and on the Prime, Gamma and ! are two different functions. From the manual:

Factorial: Factorial of a positive integer. For nonintegers, ! = ^{} (x + 1).
This calculates the gamma function.
value!

.
Gamma: Returns the value of the gamma function (^{}) for a number a.
Gamma(a)

Thus Gamma(4.5) = (5.5)! = 0.0600196013005
