## Built-in Math Functions

R also has many built-in math functions that allows you to perform mathematical tasks on numbers.

For example, the `min()` and `max()` functions can be used to find the lowest or highest number in a set:

### Example

max(5, 10, 15)

min(5, 10, 15)

## ceiling() and floor()

The `ceiling()` function rounds a number upwards to its nearest integer, and the `floor()` function rounds a number downwards to its nearest integer, and returns the result:
