it helps to visualize shifted numbers in binary. shifting left by one is like multiplying by two shifting right is like dividing in half

what you are converting looks to be just a more complicated way of setting a bunch of constants to 0,1,2,4,8,16 etc pretty common way of doing this kind of thing in C headers.

That's what I would have said. The following should do it. 

public enum type sfWindowStyle 
    sfNone         = 0, -- No border / title bar (this flag and all others are mutually exclusive) 
    sfTitlebar     = 1, -- Title bar + fixed border 
    sfResize       = 2, -- Titlebar + resizable border + maximize button 
    sfClose        = 4, -- Titlebar + close button 
    sfFullscreen   = 8, -- Fullscreen mode (this flag and all others are mutually exclusive) 
    sfDefaultStyle = or_all({sfTitlebar,sfResize,sfClose}) -- Default window style 
end type
