HP-10 (KISS) Emulator

I wouldn't go that far ;-)

My code stores the original FIX 8 number in M1 (1.239) It uses this for future operations not the FIX 2 (1.24) which is displayed, which is why I get 1.239 + .001 = 2.400

This would seem feasible for describing the 1.24 result, but I think this approach is wrong as I cannot see the original HP-10 doing what is described below.

[GOLD] 3
2.456 [+=]
[GOLD] 2
2.46
[GOLD] 3
2.460
.001 [+=]
I should get 2.461 but I get 2.457

It was hard to judge this type of behavior as the manual did not have any examples of this type of data manipulation.
