Most calculators actually use % to mean exactly that! Per-cen-tage!
On this silly CG10, % is some silly list-function thing.

Casio FX115es has proper %
Casio 9860*, just like silly CG10 does not

TI89T actually has %. You can guess what HP50G has.

Such a small insignificant thing, but it is a HANDY thing to have! and it is MISSED when
not present!

So what to do? Define a function Per(), etc? Gasp.

Any comments/rebuttals?

The percentage sign is very strange when used as an operator, how does it work on the TI ?

Does the 9860 (GII) have a percentage function? (I'll have to check it out when I get home, I've never used it.)

For instance: 100 + 5% = 105, which almost makes sense, but what would you do with 50 + 50 + 5%, if the + sign has lower precedence it would be the same answer 105 otherwise it might be 102.5 ?

As the other poster said, I think maybe getting used to writing: 100 * 1.05, then there would be no confusion about 50 + 50 * 1.05 it would be 102,5 and (50+50)*1.05 is 105.

I've never used it either, in fact, I don't believe I have seen it either. Can you give us a keystroke?
