Integer Rounding Function in Excel

Currently, there are numerous integer rounding functions in Excel such as FLOOR, Round... This can make it difficult for you to decide which function to use. To solve this problem, let's refer to the insights and solutions provided by Mytour.

Integer Rounding Function in Excel may sound simple, but executing it is not easy at all, especially when dealing with various specific rows with different functions to help you round integer numbers. Therefore, you need to thoroughly study how to use integer rounding functions in Excel as well as their functions to apply them appropriately.

Integer Rounding Function in Excel

In addition to the rounding functions previously introduced by Mytour, such as the Round function in Excel which operates quite simply based on predefined conditions, using the Round function in Excel greatly assists in current problem-solving.

If you want to round numbers down, you can use the rounddown function for this purpose. The rounddown function will lower your number series to a truncated lower value as required. If there's a function for rounding down, there must also be a function for rounding up. Hence, the Rounddup function in Excel also functions similarly to rounddown but produces larger results.

However, there is still a missing piece as we haven't mentioned the FLOOR function yet. The FLOOR function for rounding integer numbers in Excel functions to only take the integer part of the number series, removing the decimal part, remainder, and bringing the number series to even or odd numbers based on user-defined conditions. The syntax for the FLOOR function is as follows:

=FLOOR(Symbol, Argument)

In which:

Symbol: the number or cell symbol containing the number series to be rounded

Argument: fill in 1 if you want to round to an odd number, 2 if you want to round to an even number

You can refer to the image below to better understand how the FLOOR function works.

Excel's integer rounding functions like ROUND, ROUNDDUP, ROUNDDOWN, and FLOOR provide you with more suitable options according to your requirements in spreadsheets, thereby enhancing your skills. Additionally, you can use this method to round currency in Excel as well.

Furthermore, Excel offers various other mathematical functions such as basic functions like MIN, MAX, COUNT... which you'll encounter more frequently, and advanced functions like Vlookup, SumIF... which are utilized for more complex or time-sensitive problem-solving.
