Rounding up

On your calculator you will often need to round up numbers with lots of decimal places to an appropriate level of accuracy.

In the video (below) Dee Greig-Dunn, Lecturer in Mathematics and Meteorology at Solent University, explains:

  • how to round up to one, two and three decimal places
  • how to round up to a specified number of significant figures

Remember: check the size of the next significant figure. If it's 5 or over, the number will round up. If it's less than 5, the number will stay exactly the same.
