I'm not sure what the real precision of the build in functions are but it shouldn't be hard to max out a double using standard methods(even if slow, but irrelevant after the LUT has been created).
LUTs are primarily useful when you use sin(x) as a signal or when a crude approximation is good enough.
One advantage of a LUT is that you can store a more complex computation than the basic function. Like a filtered square wave.
