Zeroclickinfo-goodies: Calculator modulo operation

[wheatdog]

https://duckduckgo.com/?q=(10%5E100)+%25+10&ia=answer

(10^100) % 10 should be 0.
I am not sure why the answer is wrong. Is the symbol % represent the modulo operation?

@wheatdog Hehe, I imagine it has something to do with the way it handles large numbers :wink:

You'll be pleased to know that on the re-write (#1927) this issue is fixed:

It doesn't support % notation atm, though it would be fairly trivial to add in - I'm not sure if it has meaning outside of programming (apart from percent), so I am unfortunately biased.

@duckduckgo/duckduckhack-contributors Anyone know of any other uses? Even if we don't support the infix-operator form, we will always have the function :smile:

Modulo is a quite common function in maths as well. There is 3 main
notations I have come across.

mod(a; b)
a mod b
a % b

I think all of them would be nice to add to the calculator.

@philipmiesbauer Thanks for chiming in!

I think the first and third forms are fine, easily doable; the second would work (treating it as an operator) but I'm not sure how well it would play with _other_ infix 'functions' (though it should be fine - we use a full grammar). Updates will be on #2848 - so keep an eye out there :dolphin:

@GuiltyDolphin Great to hear that! Where can I use the re-write version of calculator? or it is not public right now.

[mintsoft]

@wheatdog it's not in a directly accessible location currently; however we hope it get it merged pretty soon!

[mintsoft]

@GuiltyDolphin @wheatdog I'm closing this because it's not likely that we'd not merge the rewrite now :)

Oh crazy world!

• calculator.pro
• SwiftCalc.app
• Yahoo
• Google, Yandex, Mail.ru & Bing can't solve it;

@wheatdog @fzzr- @mintsoft @philipmiesbauer Okay, drum roll... Here's the super complicated code to add the % and mod forms (:wink:):

And now you can do:

and

Enjoy!
