Calculating reflex and obtuse angles

Given two lines of common origin point, whose rotational angles I have in degrees, what's the best way in Lua to calculate the reflex and obtuse angles involved?

Assuming that you want the reflex angle that complements the obtuse angle, and don't worry about getting values of 90 or 180 degrees for the obtuse value:

function obtuse_reflex(a, b)
  local diff = (a - b) % 180
  if diff < 90 then diff = 180 - diff end
  return diff, 360 - diff
end
