In both cases the display has 10 digits. What do you see after 3 [1/x] 30 [x] in FIX 9 mode? 10,00000000 or 9,999999999 ?

12C+: 9.999999999
12C Emulator: 9.999999999
12CP: 10.00000000
12CP Emulator: 10.00000000

Quote:You may try this: calculate 4.444.444.444 / 3 and get 1.481.481.481. Now subtract 1.481.481.481 (or press g FRAC). On a real 12C the result is 0. But what do you get on the 12CP emulator? 0,3? 0,333? Please post all digits (i.e. as displayed in FIX 9).

12C+: 0.000000000
12C Emulator: 0.000000000
12CP: 0.330000000
12CP Emulator: 0.333330000 <=== wink, wink, nudge, nudge, say no more!
