I ended up making a full-blown fractions-calculator app:


So if you do like, [3] [OVER] [5] [-] [1] [OVER] [4] [=], it returns 7/20.

I'm not gonna post the code here though, I hope to eventually get in the iPhone Developer Program so I can sell some apps.

Ok, I didn't really look into the code much when I read it before. :P

@Hawkee, yep they show up fine now

@Gummo, Okay, but a negative denominator like 5/-3 should be fine the way it is. And obviously 5/-1 won't return -5 in this app since the answer spot is a fraction so it's not gonna spit out a whole number. But the Fraction class itself simplifies it to -5 if you use the simplify and getString methods.

@mountaindew, 5/-1 should be -5. That's what.

Let me know if you get a notice for this now.

@mountaindew, thanks for catching that.

@Gummo what's wrong with a negative denominator?

@Hawkee, these comments didn't show up in my notices page

Was going to try this out but it looks like I need to upgrade to Snow Leopard. Been putting it off until I finally have a reason to upgrade. I think this just might be my reason.

Does it fix negatives so there's never a negative denominator?
