Re: 43S Alternative key layout --> WP43C

Everything is fine, thanks for the hard work and super fast.
There are some small problems with the display update. Do you want some examples or do we postpone them to later, for the final adjustment?

Re: Standard error of forecast (error propagation in fitting?)

according to the Microsoft Excel help

The equation for the standard error of the predicted y-value is as follows:

Hi to the whole DM42 team.
There are not only grumblers in this world. There are many people who are very happy with what you do.
I am one of them and I am sure many others are too.

Re: 43S Alternative key layout --> WP43C

working with g(a b/c) in complex mode produces erroneous writing at the scientific level: after writing 3\sqrt{3}/2 and 3\sqrt{2}/2 COMPLEX, we become im3.jpg and then multiplying by -1 im4.jpg we can notice the absence of the distribution of the i on the second part of the imaginary value.

I have just encountered this problem:
after loading DM42-3.19.pmg
I need to enter the complex value (0;1) i.e. i
type 0 enter 1 f complex (MODES DEG and RECT)
I get (0;0) ? :mrgreen:
after asking the square root of -1 the bug is solved
if I reload DM42-3.19.pmg then the bug reappears :?:
