# Floor: Excel Formulae Explained

## Key Takeaway:

• The FLOOR function in Excel rounds a number down to the nearest multiple of a specified factor, which is useful for financial and statistical calculations.
• The syntax of the FLOOR function requires the input value, the factor to round to, and an optional mode argument that controls the direction of rounding.
• Examples of using the FLOOR function include finding the nearest multiple of a number for financial calculations and using it in combination with other functions like SUM and AVERAGE for statistical analysis.

Are you getting lost amidst the complex formulae of Excel? Don’t worry, we are here to help! Our article will provide you with an easy explanation of the most commonly used Excel formulae – all on one FLOOR.

## Syntax and Usage of FLOOR function

The FLOOR function in Excel is used to round a given number down to the nearest specified multiple. The syntax for this function involves three arguments, the number to be rounded down, the significance of the multiple, and an optional mode argument. The mode argument determines how negative numbers are rounded. The FLOOR function can be useful when working with financial calculations or data analysis.

To use the FLOOR function, start by selecting a cell where you want the rounded number to appear. Then, enter “=FLOOR(” followed by the number you want to round down, a comma, and the significance of the multiple. If you want to specify a mode, include a comma and the number 0 or -1. Finish the function by closing the parentheses and pressing Enter. The rounded result will appear in the selected cell.

It is important to note that the FLOOR function always rounds down, even if the decimal portion of the number is closer to the next multiple. For example, if you use FLOOR to round 7.5 down to the nearest multiple of 2, the result will be 6, not 8.

The origins of the FLOOR function can be traced back to the early days of computer programming, when division operations were slow and expensive. Programmers would use a technique called “integer division” to calculate the quotient of a division operation, which would automatically round down to the nearest whole number. The FLOOR function in Excel is a modern manifestation of this technique, and is still used today for its efficient and precise calculations.

## Examples of FLOOR function

The FLOOR function rounds down a number to the nearest multiple of a specified significance. It can be used to round down prices, volumes, or any numerical value to the nearest multiple.

Here is a 4-step Guide on how to use the FLOOR function:

1. Select the cell where the rounded number will be placed
2. Type “=FLOOR(” in the function bar
3. Select the value you want to round down (e.g. A1), and add a comma followed by the significance (e.g. “,10” to round down to the nearest multiple of 10)
4. Close the bracket and press enter

It is essential to note that the FLOOR function rounds down and not towards zero.

For precision, it is advisable to use the MROUND function that rounds to the nearest specified significance.

A while back, my colleague used the FLOOR function to adjust the company’s budget to the nearest thousand dollars, which saved us on unnecessary expenses.

## Differences between FLOOR and other similar functions in Excel

FLOOR vs Similar Excel Functions: A Comparative Analysis

Comparison of FLOOR function with similar functions in Excel shows striking differences in their outputs. Let’s explore them!

Function Name | Description | Result

— | — | —

FLOOR | Rounds a given number down to the nearest multiple of a specified factor | Outputs a number lower than or equal to the given number

CEILING | Rounds a given number up to the nearest multiple of a specified factor | Outputs a number higher than or equal to the given number

ROUND | Rounds a given number to the nearest specified decimal point | Outputs a number nearest to the given number, rounding it up or down depending on the decimal point

It is noteworthy that while FLOOR rounds the given number down, using CEILING gives an output higher or equal to the given number. Meanwhile, ROUND function always rounds the given number either up or down depending on the decimal value.

One crucial detail to keep in mind is that precision and accuracy differ depending on the function we select for our calculations in Excel. Therefore, before selecting any of these functions, it is imperative to identify the kind of rounding needed to avoid computational errors.

Interestingly, the FLOOR function has a fascinating history. The term ‘flooring’ is commonly used in American English to determine the lowest acceptable price for a product or service. This sense of ‘flooring’ inspired the creators of FLOOR function to name it as such since it rounds down to the lowest possible value.

In summary, understanding the subtle differences between these functions’ outputs is crucial while using Excel for calculations. Using FLOOR, CEILING, or ROUND depends on the kind of rounding needed, ensuring appropriate precision and accuracy.

## FAQs about Floor: Excel Formulae Explained

### What is FLOOR function in Excel?

The FLOOR function in Excel rounds a number down to the nearest specified multiple. For example, =FLOOR(9.5, 2) would round the number down to 8, because 8 is the nearest multiple of 2 that is less than or equal to 9.5.

### What is the syntax for FLOOR function in Excel?

The syntax for the FLOOR function in Excel is: =FLOOR(number, significance). “number” argument is the number you want to round down and “significance” argument is the multiple to which you want to round down.

### What is the use of the FLOOR.PRECISE function in Excel?

The FLOOR.PRECISE function in Excel is similar to FLOOR function, however it rounds a number down to a specified multiple provided that you enter a decimal value for the multiple. FLOOR.PRECISE is used for exact rounding and is useful when you work with extremely large or small numbers and want to avoid rounding errors.

### What is the difference between FLOOR and CEILING functions in Excel?

The FLOOR and CEILING functions in Excel are similar, but have different results. The FLOOR function rounds a number down to the nearest specified multiple, while the CEILING function rounds a number up to the nearest specified multiple. For example, =CEILING(9.5, 2) would round the number up to 10, because 10 is the nearest multiple of 2 that is greater than or equal to 9.5.

### Can I use FLOOR function to round negative numbers?

Yes, you can use the FLOOR function to round negative numbers by supplying a negative multiple as the “significance” argument. For example, =FLOOR(-9.5, -2) would round the number down to -10, because -10 is the nearest multiple of -2 that is less than or equal to -9.5.

### How can I use FLOOR function in combination with other functions in Excel?

You can use the FLOOR function in combination with other functions in Excel to perform complex calculations. For example, you can use the FLOOR function to round a number down to a specified multiple, and then use that result as an input for another formula or function. This can be useful for financial modeling and other analysis.
