## How do you round off 5?

In rounding off numbers, if the first figure dropped is 5, and all the figures following the five are zero or if there are no figures after the 5, then the last figure kept should be unchanged if that last figure is even. For example, if only one decimal is to be kept, then 6.6500 becomes 6.6.
