What does the 'f' do in a script when behind a float?

Because you need different things for different applications?

Making each data type the size of a long is stupid when you only need a number that goes up to 100 for example.

Also, if the compiler were to detect, it would slow the compiling process down, alot. And it will generally make your programs inefficient because a compiler may make mistakes.
