# FLOOR.PRECISE

In this comprehensive article, we will explore everything you need to know about the FLOOR.PRECISE function in Excel. The FLOOR.PRECISE function is a useful tool for rounding down a number to the nearest multiple of a specified significance. This function is particularly helpful in various mathematical, financial, and statistical calculations where you need to round down numbers to a specific precision.

## FLOOR.PRECISE Syntax

The syntax for the FLOOR.PRECISE function in Excel is as follows:

FLOOR.PRECISE(number, [significance])

Where:

• number (required) – The number you want to round down.
• significance (optional) – The multiple to which you want to round down the number. If omitted, the default value is 1.

## FLOOR.PRECISE Examples

Let’s look at some examples of how to use the FLOOR.PRECISE function in Excel:

1. Basic usage: To round down the number 5.8 to the nearest integer, you can use the formula =FLOOR.PRECISE(5.8). The result will be 5, as the function rounds down the number to the nearest integer.
2. With significance: To round down the number 7.35 to the nearest multiple of 0.5, you can use the formula =FLOOR.PRECISE(7.35, 0.5). The result will be 7, as the function rounds down the number to the nearest multiple of 0.5.
3. Negative numbers: To round down the number -3.7 to the nearest integer, you can use the formula =FLOOR.PRECISE(-3.7). The result will be -4, as the function rounds down the number to the nearest integer.
4. With negative significance: To round down the number 9.6 to the nearest multiple of -2, you can use the formula =FLOOR.PRECISE(9.6, -2). The result will be 8, as the function rounds down the number to the nearest multiple of -2.

## FLOOR.PRECISE Tips & Tricks

Here are some tips and tricks to help you get the most out of the FLOOR.PRECISE function in Excel:

• Remember that FLOOR.PRECISE always rounds down, regardless of the number’s sign. This is different from the FLOOR function, which rounds towards zero.
• If you want to round up instead of rounding down, you can use the CEILING.PRECISE function with the same syntax as FLOOR.PRECISE.
• When working with time values, you can use FLOOR.PRECISE to round down to the nearest hour, minute, or second by specifying the appropriate significance value. For example, to round down a time value to the nearest hour, use a significance of 1/24 (since there are 24 hours in a day).

## Common Mistakes When Using FLOOR.PRECISE

Here are some common mistakes to avoid when using the FLOOR.PRECISE function in Excel:

• Not specifying the significance value when needed. If you want to round down to a specific multiple, make sure to include the significance value in the formula.
• Using the wrong function for rounding. If you need to round up or round to the nearest multiple, consider using the CEILING.PRECISE or MROUND functions instead.
• Forgetting that FLOOR.PRECISE always rounds down. If you need to round towards zero, use the FLOOR function instead.

## Why Isn’t My FLOOR.PRECISE Working?

If you’re having trouble with your FLOOR.PRECISE formula, consider the following troubleshooting tips:

• Check your formula syntax. Make sure you have the correct number of parentheses and commas.
• Ensure that the number and significance values are valid. If you’re using cell references, make sure they contain valid numbers.
• Remember that FLOOR.PRECISE always rounds down. If you need different rounding behavior, consider using a different rounding function.

## FLOOR.PRECISE: Related Formulae

Here are some related formulae that you might find useful when working with FLOOR.PRECISE in Excel:

1. FLOOR: The FLOOR function rounds a number down towards zero to the nearest multiple of a specified significance. Syntax: =FLOOR(number, significance)
2. CEILING.PRECISE: The CEILING.PRECISE function rounds a number up to the nearest multiple of a specified significance. Syntax: =CEILING.PRECISE(number, [significance])
3. MROUND: The MROUND function rounds a number to the nearest multiple of a specified significance. Syntax: =MROUND(number, multiple)
4. ROUND: The ROUND function rounds a number to a specified number of digits. Syntax: =ROUND(number, num_digits)
5. TRUNC: The TRUNC function truncates a number to a specified number of decimal places. Syntax: =TRUNC(number, [num_digits])

In conclusion, the FLOOR.PRECISE function is a versatile and useful tool for rounding down numbers in Excel. By understanding its syntax, examples, tips, and related functions, you can effectively use FLOOR.PRECISE in your calculations and avoid common mistakes.
