HP 49g+ Message #1 Posted by Pascal Jerney on 16 Oct 2004, 11:00 a.m. Hi there! I own a HP 49g+ Calculator and I have a problem: When I bought it, i wanted to test it and calculated the factorial of 1000. No problem, after 30 seconds I had the result with all digits. But now, 2 days later, if I want to calculate this factorial again, the calculator only shows 9E499 or shows the "Overflow"-Error if system flag 21 is turned on. Please help me! Pascal
