Google Sheets FLOOR.MATH Function: Syntax, Examples & Tips

number:
The numeric value that you want to round down to the nearest multiple of significance.

significance:
(Optional) The multiple to which you want to round down. If omitted, the default value is 1.

mode:
(Optional) A value that determines how to handle negative numbers. If omitted, the default is 0, which rounds towards zero. If set to 1, it rounds away from zero.

What is FLOOR.MATH?

The FLOOR.MATH function in Google Sheets is a mathematical function used to round a number down to the nearest integer or specified multiple. This function is particularly useful in scenarios where you need to ensure that values are rounded down to avoid exceeding a certain limit or to comply with specific requirements in calculations.

In simpler terms, FLOOR.MATH allows you to control how numbers are rounded down, making it easier to manage numerical data in your spreadsheets.

A Practical Example

Imagine you are managing a budget for a project and need to allocate funds based on specific criteria:

Budget Table:

You want to round down the costs to the nearest whole number for reporting purposes.

FLOOR.MATH Formula

To achieve this, you would use the FLOOR.MATH function as follows:

=FLOOR.MATH(B2)

In this formula:

• B2 is the cell containing the cost from the Budget Table.

Result of the Formula

When you apply the FLOOR.MATH formula to the Budget Table, the output would look like this:

The FLOOR.MATH function rounds down each cost to the nearest whole number, making it easier to present the budget in a simplified format.
