What is a rune?
...
Rune literals are just 32-bit integer values (however they're untyped constants, so their type can change). They represent unicode codepoints. For example, the rune literal 'a' is actually the number 97.

What's the difference between using CGFloat and float?
...e types were introduced to make it easier to write code that works on both 32-bit and 64-bit without modification. However, if all you need is float precision within your own code, you can still use float if you like — it will reduce your memory footprint somewhat. Same goes for integer values.

I ran into a very similar issue.
I needed to use an old 32-bit DLL within a Web Application that was being developed on a 64-bit machine. I registered the 32-bit DLL into the windows\sysWOW64 folder using the version of regsrv32 in that folder.
Calls to the third party DLL worked...

How do I convert a decimal to an int in C#?
...
Use Convert.ToInt32 from mscorlib as in
decimal value = 3.14m;
int n = Convert.ToInt32(value);
See MSDN. You can also use Decimal.ToInt32. Again, see MSDN. Finally, you can do a direct cast as in
decimal value = 3.14m;
int n = (int) value...

Why do people say there is modulo bias when using a random number generator?
...g new random numbers until the one
* returned is outside the range [0, 2**32 % upper_bound). This
* guarantees the selected random number will be inside
* [2**32 % upper_bound, 2**32) which maps back to [0, upper_bound)
* after reduction modulo upper_bound.
