This is a very nice demonstration of many languages, most of which I've never heard of.

Yay for me, I've heard of at least 60% to 70% of them. However the number I can code in is only a handful and the number I've any real experience with is even less. Back on-topic, it's not surprising that a problem like that is solvable. With the abilities to use logic and iterate through a pattern, computers can solve most problems mathematically.

It's easy to forget just how unusual COBOL was, looking at it now it's almost like the code is making demands - if Skynet was real, it would be written in COBOL.

Can anyone add an industrial-standard language to the list that isn't there?

I have worked for years with RPG/400 and RPG IV. here is the code is RPG IV:

I hated coding in cobol. Never again I said!

I came across a method recently that made clever use of an array and modulo for an iterative method.




This method is non-iterative nor recursive, but seems to lose precision after the 32nd number in the series. Maybe a DB limitation?

I was surprised to see ALGOL and PL1 absent from that list - and also amazed to see Cobol mentioned.

You're using floats - bound to give problems in an iteration like that.

I would guess:

sqrt(5) ~ 2;
232 is 32-bits, so I'm guessing this breaks down because floats are stored in 32 bits? (Are they? Not actually certain on that.)

Typically floats are stored as dwords (doublewords, 2 bytes per word, so 4 bytes, or 32 bits)
