The History of "i" [modified]

I thought i/j/k were commonly used in mathematical circles, and so they just moved in to code. Christian Graus - Microsoft MVP - C++

Much like hungarian notation, which I happen to like (I'm not hungarian), but am slowly being converted to camelCase (I'm not a camel either).

I normally throw spaghetti up against the wall. Then, when I see an interesting pattern, I write it down. And that's how I discover new letters. Coming up with the pronunciation for those letters is a little difficult though. :rolleyes:

Give the spaghetti to someone who eats with their mouth open and listen to the interesting sounds that emerge :)

This brings back memories from the times there was no i.

The possibilities are transcendental when you get David and Ryan going on Mathematics. Add in Chris and well... somehow it all equals "i" in the end...:laugh:

I think I reserved i for 2 people at 7:00. :doh:

You know the ubiqious "i" found in almost every example of a for loop for newbies? On another forum were having this disscussion (sorta)... I said (I believe I read it in an C K&R book) that it's because it's simply an alias for Index which is what "i" is usually doing in a for loop...?? Someone else says it has to do with: They are from general Summation Notation that, like many other mathmatical notations, worked its way into early languages -- specifically Fortran (remember its FORMula TRANSlation) I never would have guessed :P Cheers :) It's frustrating being a genius and living the life of a moron!!! -- modified at 21:18 Wednesday 4th October, 2006

It depends. In electrical engineering, i is reserved for alternate current and, hence, we use j to refer to sqrt(-1). Francisco Silver at last!!

It started here: n Σ i=0 the mathematical equivalent to:
for (i = 0; i <= n; i++) {
}Note the terminating condition, as the mathematical expression Σ includes the terminating value.

You do realise that as a mathematician it's my duty to insert lots of engineer jokes, right? ;) I'll let you off with a warning this time. cheers, Chris Maunder

"i" because it's automatically treated as an integer in Fortran--the first of several automatic integer variables, followed by "j", "k", "l", etc. I can't remember how many letters are allocated to be integers.

Don't worry, I know quite a number of mathematics jokes. I suggest we call it even and stop this thread right here to avoid possible casualties should we start the war. :-D Francisco
