Comment 7 for bug 1332567

Ok, an update: in image #97 isn't fixed, but the bug has a very strange behavior:
- connect the device to computer,
- open the calculator,
- do 1/3: results is 0.3,
- close the app,
- disconnect the cable from the computer,
- reopen the calculator,
- do a calc,
- close the app,
- reopen the calculator
- do again 1/3
- result is 0.33333333, as expected

Seems that the calc is wrong if the device is connected to the pc
