Syntax of the formula
=FLOOR (number, multiple)
=MROUND (number, multiple)
Understanding the formula
- The FLOOR function is fundamental when it comes to rounding a number down to the nearest multiple.

- While we can also use the CEILING function, this will round a number up to the nearest multiple, and not down.
The FLOOR function can be specifically used to round down prices, times, instrument readings and many other numeric values.
