[lua]

local decimalValue = function (val, places)

      local factor = 1

      for i = 1 , places, 1 do

            factor = factor * 10

      end

      local rounded = math.round(val * factor)/factor

      return rounded

end

print (decimalValue(CircleonTransition.x, 1 )) – one decimal place

print (decimalValue(CircleonTransition.x, 2 )) – two decimal places
