Hello!

I'm thinking the following "lack" of 9860. They have dilligently made the multi line "natural textbook display" and if you want to make nice looking division you have to use ab/c-button (when math-mode on). If you press normal division button, it show's calculation like older calculators does..??

I'd like that if i'll push division button, the calculator understands that i'm going to divide and draw nice looking division line like ab/c button does.

And if you type for example: 5 and then ab/c it won't make a division line, so you have to know beforehand that you're going to do a division and push ab/c beforehand. That's irritating!

Is there any kind of solution to that "lack"?? It wound't be so hard to create a mod which repairs this.

I think this is no lack but a feature. I'm not sure though.

I think 5 [a-b-c] 3 [a b c] 2 means

5 / 3 / 2 (so ultimately 5/6)

whereas 5 [ -:- ] 3 [a b c] 2 means

2,5 / 2

This could be for easier and faster input without brackets and seems logical to me. don't own an 9860 though ...

In the 9860 you can not use the form: n (abc) x (at least while using natural input display).
you have preveously to declare a fraction :
(abc)
5
(down key)
2
= 5/2.
The problem is that when you for instance forget that the whole thing you just typed out was suposed to be under a fraction bar, you can't just go back and type it like in the linear formula input.
It is not an error, or lack of thought however, that the standard Divide key, does not auto frac, as it is impossible to know in the behing expression what is to be over the fraction bar and what not.
So, the system implemented by casio was that you would have to input the right thing in the right field.
Until an SDK is launched i don't believe that such thing can be done... thought providing that an SDK is launched we may use" () " to limit the expression for the auto frac... It is something to be thought in the future, as it would be very usefull indeed.

It works!
thought not exactly as you put it there... the result indeed is correct, if you press enter... that does not make the 5 go down in the input... but it works... the reult is the same.
