New firmware for the Swissmicros DM15L

[Helix]

I’ve found other minor inconsistencies in display format for real numbers.

With FIX 13:
7 1/x gives 0.1428571428571 so as expected 13 digits after the period.
But then CHS gives -0.142857142857 so only 12 digits.

With FIX 14, negative numbers are still displayed with 12 digits.

With SCI 10, we have -1.428571429E-1 so only 9 digits after the period.
With SCI 11, we have the same display.

The same problem occurs with ENG mode.

There is perhaps a more serious problem with ENG mode: it sets the number of digits after the period, whereas in the HP15C it sets the number of significant digits.
For example in ENG 4 mode, 7 1/x is displayed 142.8571E-3, whereas the HP15C displays 142.86E-3
This affects the result of a subsequent RND function.
