Try 1 / 2x10^3 to get the wrong answer 500. ( 1 divided by 2000).

Type 1, division function, 2 then the x10 button at the bottom, 3, EXE.

The 991 EX gives the correct answer. So do my HPs ... . This upgrade is complete nonsense.

For the CW, as illustrated in another thread I posted, I came up with a bit of a workaround.


Here’s the gist: place the value in parentheses. For example, log 19E5 / e^2E20 should be entered as log ( 19 [x10^x] 5 ) / e^ ( 2 [*10^x] 20 ) EXE
