1234.56789: 1.2346E3

and so on. So ENG 4 actually shows 5 digits and has nothing to do with "decimal places". What was the first place it started behaving like this?

It's the same on my 41C. I think that the reasoning behind this is to display the same number of digits in SCI n and ENG n:

123.456789: 123.46 E00 in ENG 4
123.456789: 1.2346 E02 in SCI 4

From the 41C manual (http://www.greendyk.nl/hp41c-manual/index.php?p=34) :

Quote:Engineering notation is selected by pressing f ENG followed by a number key. The first significant digit is always present in the display, and the number key specifies the number of additionnal significant digits to which the display is rounded. The decimal point always appears in the display.

123.456789: 100. E00 in ENG 0
123.456789: 1. E02 in SCI 0
