Here is a simple static method to do this in C#:
public static string ToTitleCaseInvariant(string targetString)
{
return System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(targetString);

In PHP it is:

What I was thinking of can be achieved using list comprehensions, but I thought that there was a function that did this in a slightly neater way.

foo in iter_attr(bar, 'id')</code></pre>

I think it's because it's a creator method (not sure if there's a better name). All it does is take what you give it and return a single string object. It doesn't operate on an existing object. If it was non-static, you would need a string to begin with. |
Because the Format method has nothing to do with a string's current value. The value of the string isn't used. It takes a string and returns one. |
I am no authority in JavaScript, and perhaps more of a dunce than the asker, but AFAIK, the difference is that the "javascript:" prefix is preferred/required in URI-contexts, where the argument may be as well a traditional HTTP URL as a JavaScript trigger.

Your python interpreter is correct.
One (Stupid) way of calculating a modulus is to subtract or add the modulus until the resulting value is between 0 and modulus -1.
e.g
13 mod 5 = (13 - 5) mod 5 = (13 - 10) mod 5 = 3
or in your case
-2 mod 5 = (-2 + 5) mod 5 = 3 |
Well, -2 divided by 5 would be 0 with a remainder of 3. I don't believe that should be very platform dependent, but I've seen stranger things. |
It is indeed 3. In [modular arithmetic][1], a modulus is simply the remainder of a division, and the remainder of -2 divided by 5 is 3.
[1]: http://en.wikipedia.org/wiki/Modular_arithmetic |
The result of the modulus operation on negatives seems to be programming language dependent and here is a listing http://en.wikipedia.org/wiki/Modulo_operation |
Well, 0 % 5 should be 0, right?
-1 % 5 should be 4 because that's the next allowed digit going in the reverse direction (i.e., it can't be 5, since that's out of range).
And following along by that logic, -2 must be 3.
The easiest way to think of how it will work is that you keep adding or subtracting 5 until ... |
