HP-10 (KISS) Emulator

[[kby]]

I haven't read the manual, but I'm sure this isn't in there. It is an odd effect of the fact that the HP-10 (sort of) rounds internally to the display. Unfortunately, I don't have access to Windoze machine to actually try the emulator, so I post this for those who might wish to try (and report back) with the emulator as wella s other HP-10s. Key sequence:

Code:

Keys             Displays              Comments
<Gold> 3          0.000                ;set display to FIX 3
1.240             1.240                ;enters number
+=                1.240
.001               .001                ;enters .001
-                 1.239                ;Subtraction
<Gold>2           1.24                 ;sets display to FIX 2; also rounds number
<Gold>8           1.24000000           ;FIX 8
.001               .001
+=                1.24000000           ;!

Note that directly adding 1.240 + .001 yields the expected 1.241.

Another oddity: MR always displays in Automatic (floating decimal point) mode,
regardless of the current display mode.
