Bounds

• The upper bound is a recurring number for example 16 to the closest 1 has an upper bound of 16.49999… so we use 16.5
• The lower bound of a number is simpler. The lower bound of 16 to the closest 1 is 15.5 as it will round to 16 when to the closest whole number.
• We can say 15.5<_x<16.5. So there could be an error as large as 0.5
