CAS Settings
hi everybody,
I didn't find in the PDF Guide the default value for the CAS Settings values on page 2 (Recursive evaluation, replacement, function, epsilon, probability, newton)
Are they the same for Emulator and the Prime?
Sure I made sono tries and now they are different.
There is a way to get the default values with our reset the calculator?

Thanks!
salvo

RE: CAS Settings

found!

CAS Settings (shift CAS), then shift+Esc (Clear)

Recursive evaluation 5
recursive replacement 1
recursive function 100
Epsilon 0.000000000001
Probability 1E-15
Newton 60

Aren't they?

Strange to tell, the original defaults (in a brand-new machine, or after a total memory reset) are slightly different from the Shift Esc (Clear) values:

After total memory reset: 5, 1, 9, 1e-12, 1e-15, 40.
After Shift Esc (Clear): 5, 1, 100, 1e-12, 1e-15, 60.

The "total memory reset" values also seem to reappear after an Apps+Esc+On warmstart, which may or may not perform a total memory reset, depending on your firmware version, the phase of the moon, and Murphy's Law.

I don't know, Joe, it's a mystery also for me...
between 9 and 100 there is *only* a little difference ;-)
So which values are the most suitable?
