hp49 en hp50 qgrdne Unregistered Posts: 3 Threads: 1 Joined: Nov 2011 02-04-2013, 08:00 AM Mode RPN, for the hp49 and hp50. I used the following command: '2^2^2^2' The result is: 65536. The answer should be: 256 With the hp48 (and hp85) I get the result 256. Any idea why the HP-49 and HP-50 gives this result (65536)?
