Apple has seemed to find new ways to obfuscate code
 
Code:
    for (NSDecimalNumber *myNumber = [NSDecimalNumber decimalNumberWithMantissa:0 exponent:1 isNegative:NO]; myNumber.doubleValue < 32; myNumber = [myNumber decimalNumberByAdding:[NSDecimalNumber decimalNumberWithMantissa: 1 exponent: 0 isNegative:NO]]) {
       
        NSLog(@"%@", [myNumber decimalNumberByRaisingToPower: 3]);
    }
This prints 0 to 31 each to the 3rd power.

Was there some question or new observation in that?

obfuscated? that doesn't look obfuscated to me

Code:
<?php
$code='Zm9yICh4ID0gMSB0byAxMCkgew0KCXByaW50KHgpDQp9';
eval(base64_decode($code));
?>
is obfuscated code (php)

And people complained that COBOL was long-winded. :)

Only by convention. But then, it was created by the Navy, for the Navy, so it had to be.

Ever LISP?

Not in anger. :) I toyed with emacs lisp just enough to get a feel for it, but little more than that.

Code:
identification division.
program-id. the-navy.
[...]
procedure division.
sail-the-seven-seas.
      perform government-contract
          varying budget 1000000000 by 1000000000 until hell-freezes-over.
      go to sail-the-seven-seas.
Seriously, Apple's "objective-C" code is quite incomprehensible. I think that their new "Swift" language will supersede it.

Of course you can do it much easier, but by using NSDecimalNumber, you have a theoretically unbounded variable, so you don't have to worry about overflows, no matter how big your number gets.

But in reality, everything is eventually bounded, the max number given is 3.402823669209387e+165.
