When you think about it, dividing by zero should equal infinity. When you say 4/2, you ask, "how many two's go into the number 4?" The answer is of course 2. When you say 4/0, you ask, "how many zeros go into 4?" As 0*0*0*0... will always equal zero, the answer is Infinity.

That's actually a good way of illustrating it. I'm still not changing from divide by zero being infinity, as that's how many languages handle it. That, or NaN errors.

I have one suggestion:

Please use normal numbers for the outcome, because I can hardly read them. You should do a poll if you are going to do this

no, you cant devide by zero
its undefined

YOU CAN IN PROGRAMMING! DEAL WITH IT!

[PixelToast]

no you cant, you just simply check for it
if you REALLY devided by zero it would just loop forever

[Lightning101]

How about the M+ key you get on a lot of calculators?
Or a square root function using math.sqrt?

Still not gonna change it. Learn to love it.

The memory key was a pain to try to add, but there is a square root function already implemented. And it does use math.sqrt.

Can I use this in my OS? Also If I did how would I change it, because I can't find the "OFF" button code.

I will find a way to error it it shouldnt be to hard im the master at spamming numbers.

you sure?
because everything is error checked

The code to exit the program is on lines 273 — 278 ... but I don't understand why you would want to change it ...

How many 2's in -4? It's -2. How many 0's go into -4? It will be negative infinity.
So, using your logic, dividing with zero will not always give you positive infinity.
And what about this:
4/2 = 2
8/2 = 4
4 > 2
Therefore 4 and 8 are not equal.

Using your logic:
4/0 = INF
8/0 = INF
INF == INF
Therefore 4 == 8???

Also, consider this. Since division is the reverse of multiplication, take this for an example:
8/2 = 4
8x4 = 2

8/0 = INF
8 x INF = 0??


Any number divided by 0 is undefined.
But since it returns infinity in Lua, I think this calculator should keep it for consistency.

Does it have scientific notation?
Like when you do 9999999 x 99999999 would answer 999999890000001,
then in scientific notation it would be
9.99999890000001 x 10(14)
The (14) is what the 10 is powered to.

You quite expertly rose this topic from the dead. I don't really support this calculator anymore, but if you'd like to fiddle around with it, you're more than welcome.
