[C#,Math] Anyone think they can do this better?

I tried for an answer at Yahoo! answers and figured no one would answer. Which was exactly what happened. So I'm here because I know that some of the most brilliant mathematical minds I've met are here. Anyways, here's me quoting, well, me. For the most part anyway.

I'm trying to see if there's an easier way, mathematically, to take in a number, and then get it's output based on an adding system of what I have written below. Going in order, adding each time. 256, add 1 time 128, add 1 time 64, add 2 times 32, add 4 times 16, add 8 times 8, add 16 times 4, add 32 times 2, add 64 times 1, add 128 times Examples 1 would be 256 + 256 2 would be 384 + 128 3 would be 448 + 64 4 would be 512 + 64 5 would be 544 + 32 ... 50 would be 968 Here's the code I made in C# to do it. But I feel having to run through the loops for bigger numbers, for instance, would take a bit of strain on certain computers. private int Generate(int intNumber) { int intAddTo2 = 0; int intOutput = 0; if (intNumber != 0) { for (int intAddTo = 256, cnt = 0; intNumber > cnt; cnt++) { intOutput += intAddTo; if (intAddTo2 % 128 == 0) { intAddTo /= 2; intAddTo2 = 0; } intAddTo2 += intAddTo; } } else { intOutput = 0; } return intOutput; }

I'll accept an answer in any language someone writes an answer in, within the boundaries of a high level programming language, and not Brain Fuck or anything like it. That is, if there is a better way to do this. In my head, I always believe there's a better way to do something. For this though, I think I may have hit the pinnacle of a way to do this.
