The TI-34 is a fairly basic scientific #calculator.

My fuzzy brain vaguely remembers fpart() being handy for "clock arithmentic", converting decimal hours into minutes, for instance. And similarly for converting decimal feet into inches and decimal inches into fractions.
But it seems like there was a more useful trick involving "slide rule math", something to do with fractional exponents, but I can't remember the specifics. Ring any bells?
@jakebrake @futurebird To some extent I could see such things, but remember, this is a scientific calculator. That means everything you punch in you're doing by hand. Really, at that point it's easier just to type in the decimal part in parenthesis where needed.
Actually, I'm just not sure how you could use that well on a scientific calculator. It only truly makes sense when working with variables.

It does have a little “operations” button where you can define a function with one variable.
Maybe it could be used with that?

@futurebird What does the TI-BASIC version of `int` return? Perhaps they're trying to match the expected result?
I’m showing what TI basic would return.

@futurebird Uh, sorry I'm dumber than usual today. Perhaps I should wait for the rest of the post to load before commenting
nah it’s not you this is a little confusing— and I wonder if it should be considering these are educational devices.
I do think part of the problem is “int” is a type in python— but it’s just an operation on the calculator.

You see this is why I don’t like this even if I can explain why it happens.

@futurebird they are doing what would generally be expected in their domains. a person using the calculator is unlikely to think of a float as an integer and fractional part, while a programmer is quite likely to think like that
@risc Ok but that calculator also runs python which means you can get both results on the same device you hand to children.
