UInt32

UInt32 stores values from 0 through 4_294_967_295.

local flags: UInt32 = 1_024
local doubled = flags * 2
local description = `value={doubled}`

rc.3 implements arithmetic and ordering, but not bitwise operators or shifts. Use UInt32 for an integer value with this representation, not as a promise of a bit-mask API.

Int64(flags) is an exact checked integer conversion because every UInt32 value fits in Int64.
