How to Use the FLOOR.PRECISE Function in Excel

Today, we’ll explore the FLOOR.PRECISE function available in both Microsoft Excel and Google Sheets. This function rounds down a given number to the closest multiple of a specified signficance, towards zero. It effectively differs from the classic FLOOR function by accommodating non-integer multiples.

Syntax

The syntax for the FLOOR.PRECISE function is uniform across both Excel and Google Sheets:

FLOOR.PRECISE(number, significance)

number: The numeric value that you need to round down.
significance: The multiple to which the number will be rounded down.

Example 1: Basic Usage

To better understand the FLOOR.PRECISE function, let’s look at an example. Assume we have the number 15.75 and we wish to round it down to the nearest multiple of 5. We would use the formula:

=FLOOR.PRECISE(15.75, 5)

The result, in this case, will be 15, since 15 is the nearest multiple of 5 that is less than or equal to 15.75.

Example 2: Negative Numbers

Importantly, the FLOOR.PRECISE function also handles negative numbers effectively. For instance, if we need to round down -8.25 to the nearest multiple of 3, the formula to use would be:

=FLOOR.PRECISE(-8.25, 3)

Here, the result will be -9, as it is the closest multiple of 3 that is less then -8.25.

Example 3: Using Cell References

Additionally, the FLOOR.PRECISE function can utilize cell references. For example, if cell A1 contains the number 24.6 and cell B1 stores the significance value of 7, to round down 24.6 using these references, the formula would be:

=FLOOR.PRECISE(A1, B1)

Placing the significance value in a separate cell enhances the flexibility and reusability of your formula.

In summary, the FLOOR.PRECISE function in Excel and Google Sheets offers a convenient way to round numbers down to specified multiples, which can be particularly useful in financial and mathematical applications requiring precise rounding adjustments.
