# synonym of rounding off to the nearest whole number

Hi can you please suggest a synonym of the following sentence "rounding off to the nearest whole number"

A rounded number can be called an approximation. You could say 34.9 is approximately 35, or the "~" symbol can be used rather than writing out "approximately" when doing math. Ex.: 34.9 = ~35.

you have two choices:

round up - to raise a number to the nearest whole number or ten, hundred, or thousand above it.

`2.7` rounded up is `3`

OR

round down - to lower a number to the nearest whole number or ten, hundred, or thousand below it.

`2.7` rounded down is `2`

you can also use a ceiling function - which is a function that takes real number (any number that can be put on a number line, including decimals) and maps it to the nearest whole number above it (or to the right of it when visualizing a number line).

or, use a floor function - which is a function that takes a real number and maps it to the nearest whole number below it (or to the left of it when visualizing a number line).

usages: the floor function of `2.7` is `2` and the ceiling function of `2.7` is `3`.
