## TOPICS RELATED TO ROUNDING NUMBERS

### How do you round off numbers ending in 5?

In rounding off numbers, if the first figure dropped is 5, and all the figures following the five are 0 or if there are not any figures after the five, then the ultimate figure stored must be unchanged if that closing parent is even. as an instance, if most effective one decimal is to be stored, then 6.6500 turns into 6.6.
