Daniel, thank you for commenting. For some reason the emulator doesn't work the same at my end. I am using Virtual HP-41, Release 8, running on 32-bit Win10. And I have jyst checked the V41 relase 7B (freshly downloaded from this site), and the behaviour is identical. Typing 100000 [Enter] * results in 1.0000 (with [FIX] 4), no exponent value. When I turn on exponential notation ([SCI], 4), typing 1 [EEX] 5 (i.e. 1 * 10^5) the screen correctly ... (read...)

My issue has ben solved replacing batteries for new ones. mine has two cells of CR2032 and when they are in end of life the calculator works fine for single operations but will not work for programming calculation - if any key for complex calculation is depressed as PV, PMT etc the HP12c will turn itself off, and when turned on will show PR ERROR - As I understand, the HP12c spend more power for complex calculation. So low charge batteries will not support the task. (read...)
