but how can something be approximately an int? Either is or it isn't ;-)
I vote for "->I".
Well, the question is whether from 1.45 to 1 it is a conversion or an approximation ... topic for another day ...

Another option would be to have ->N, with N the mathematical notion for natural numbers.
I know you won't want to change ab/d, but in this vain it could become ->Q with Q the mathematical notation for the rationals.
You know me already ... I want to stick with Walter's description in his manual for that - there is enough for me to document in the differences already ...

Maybe a glyph for the arrow to save space? I agree that the concept is more of a conversion than an approximation.
I have a rubber arm ... look ...

Two letters, that's what I wanted, any comments on this version?

The natural numbers exclude the negatives. And the integer types in the calculator include negatives.

Strictly speaking the number set would be Z but I also don't want to go there.

Most correct would be LI for long integer referring to the type, but I want to shorten it, not make it longer.

I like [≈I] for the reason noted above, it's a reminder that it is approximating the number with an integer. Self-documenting is good.

But [->I] is nearly as good, reinforcing that the input is being changed.

Close, but a small lean towards [≈I]

It is a projection from R to N.

Hi Bob, thanks, I hear your point and find that approximation is good, whether a projection or not (out of my field ;-) ), but considering the two screenshots that I sent, I now prefer [->I] for the reasons that the arrow intuitively indicates movement where the ≈ does not, in the same way that the arrows used at >R and >P (located on the opposite side of the same row). Also the arrow is in line with the existing longinteger<>shortinteger conversions that I already have in the HOME / UP menu (see below),

Looking at this menu:
  • ->I means a conversion/projection/rounding to a long integer :)
  • Then SI<-<- means a double backwards conversion to a short integer, doesn't it?
  • And ->->LI means a double conversion to a long integer, doesn't it?
  • But I have absolutely no idea what ->LI<->SI shall mean. :?
Thanks in advance for enlightenment.
