ENG mode, n+1?

[Steve Simpkin]

Wow! As an Electrical Engineer I have used ENG mode in HP calculators A LOT over the past 36 years. I used my HP-25 for 10 years before moving on to newer HP models and never really paid close attention to the differences in ENG display mode. I typically used ENG 2 on my HP-25 to obtain 2 digits of precision beyond the 3 potential significant digits shown in ENG mode. This more or less mimicked the FIX 2 mode that the HP-25 defaulted to every time it was turned on. On later models I would use ENG 4 to achieve a similar display.
I am just glad I never used ENG 1 or ENG 0 on the newer models. Having 149 millivolts displayed as 100.E-3 or 150 milliamperes displayed as 200.E-3 is not good. I understand why it does this but I don't like it.
