How to make a calculator that divides by zero? Answered

Hi
New to the forum so not sure how it works here but basically asking a request for a instructable for any shop brought calculator that when asked to divide something by zero returns a number, maybe a  random number, but hopefully 42 everytime. Is this possible and if so could someone post the instructable?
Cheers

0.99999 repeating is understood to equal 1.

I remember at one time thinking that

1/0 should equal infinity. but NO. It doesn't.

But what if 0 is defined as

0.0000(repeating infinitely) followed by...001

Then 1/0 (as we have defined "0" will = infinity.

You can draw the division symbol on the screen with a whiteboard marker...

Zaphod Beeblebrox will certainly have one or two to spare but you might have to drink a few pan galactic gargle blasters with him...
If you have the time to read in the arduino playground then of course you could use a keypad, display and an arduino to create your own calculator.
Apart from the normal functions just add an extra call for a devicsion by zero to show whatever you want.
Don't forget your towel...

I was hoping it would be possible (and not too difficult) to reprogramme any normal calc brough from a shop. Wanna give one to a math 'geek' friend.

If anyone can advise on this, cool.

Thought I deleted the first post after seeing the wanted forum.

Anyone else wish to reply with something more productive for my 'nonsense needs'?

You could program your own to run on Android or IOS...

There is neither a need for nonsense calculators nor to post the same nonsense twice.
I mean: Why not just ask for a lightbulb that draws light in instead of emitting it....
Sorry but getting fed up by newbies constantly crewating double postings and never hearing from them again....
