Example:

If the last digit dropped is 6,7,8,9 then the last digit retained is increased by 1.If the last digit dropped is 0, 1, 2, 3, 4 then the last digit retained remains the same. If the last digit dropped is 5 then remaining digit is rounded to nearest even number.

Measurement error happens when we measure physical quantities, because humans and devices are not perfect. For example, we measure length of book to be 23.1 cm by using ruler. The device error is half of the smallest unit on the scale. The smallest unit on the ruler is 1 mm; therefore error is 0.5 mm. Our result will be written like this:

Length of the book we have measured is uncertain and lies between 23.05 cm and 23.15 cm.
