It's a float. Integers can't have commas.

Excuse me, I was just taking that by the name, it seemed weird to me too D:

C is a programming language which is, before running, converted into machine code and then packed into an "exe" file. That's called "compiled language".
Machine code is system-dependent and needs to be compiled differently for each system(Linux, Windows, Mac) [x86, x64]
Python, for example, is a programming language which is converted into machine code during runtime, meaning the programs are saved as ".py" files or "scripts". That's called "interpreted language".
C is favored over Python for its ~ 20-30x improvement in speed. Python is favored over the simplicity of writing code and speed of development.
It's an arms race, basically.

Powder Toy is written in C. This means it has to be compiled before launching. That's what lets it update 235 008 * 4-5 layers of particles, around 60 times a second.
It can basically be made to compile on runtime, but that'd mean the startup of the program would take anywhere from 20 seconds to 2 minutes and it'd all be handled by a Python script or a simple batch file. Plus you'd require to have a compiler on your system.
Actually, even I could make that.
