There are four main methods for rounding in Excel: 1. Use the ROUND function for standard rounding, which is suitable for most conventional scenarios, such as ROUND(3.14159, 2) to return 3.14; 2. Use ROUNDUP and ROUNDDOWN to achieve directional trade-offs, suitable for scenarios with specific directional needs, such as ROUNDUP(3.2, 0) to return 4; 3. The cell formatting only changes the display effect, does not change the actual value. If you want to retain the real value, you should use the ROUND function and copy and paste it as a numeric value; 4. Use IF and other functions to implement conditional rounding, such as IF (A1>1, ROUND(A1, 0), A1), to improve data analysis flexibility. Mastering these methods can effectively deal with numerical formatting problems.

When processing data in Excel, numbers are often rounded to improve readability or meet specific formatting requirements. Mastering several commonly used rounding methods can make your data sorting more efficient.

Standard rounding using ROUND function

This is the most common and recommended method. The ROUND function rounds the numbers according to the specified number of digits. The basic syntax is:

=ROUND(數(shù)值, 小數(shù)位數(shù))

for example:

• =ROUND(3.14159, 2) will return 3.14
• =ROUND(A1, 0) will round the numbers in A1 to integers

If the second argument is a negative number, it can also round the integer part:

• =ROUND(1234.56, -1) Returns 1235 (rounded to ten digits)
• =ROUND(1234.56, -2) Returns 1200 (rounded to hundreds)

This function is suitable for most common scenarios and is recommended to use it first.

Use ROUNDUP and ROUNDDOWN to make directional trade-offs

Sometimes you may not need standard rounding, but rather you want to round up or down uniformly. At this time, you can use ROUNDUP (always carry) and ROUNDDOWN (always abandon).

They are used in a similar way to ROUND:

• =ROUNDUP(3.2, 0) returns 4
• =ROUNDDOWN(3.9, 0) returns 3

Examples of application scenarios:

• In financial calculations, you should conservatively estimate income, and you may use ROUNDUP.
• Inventory management, ROUNDDOWN may be used

These two functions are suitable for scenarios with specific directional requirements and are more controllable than ROUND.

The difference between shortcut keys and cell formatting

Many people mistakenly think that adjusting the decimal places by "setting cell formatting" is real rounding, but it is not. This method only changes the display effect and does not really change the value itself.

If you want to quickly round and keep the values:

• You can use the ROUND function to generate a new value first
• Copy these results and use Paste Special - Values to overwrite the original data

In terms of shortcut keys, Excel does not have the default rounding shortcut key, but you can customize macros to implement it.

Tips: Rounding conditions based on IF judgment

In some cases, you may only want to perform rounding when certain conditions are met. For example, only processing numbers greater than 1 can be done:

=IF(A1>1, ROUND(A1, 0), A1)

Similarly, ROUND and other functions (such as SUM, AVERAGE) can also be combined to make the calculation result cleaner.

Although this type of combination is a little more complex, it is very practical in actual data analysis and is worthy of mastery.

Basically these are the methods. After mastering the ROUND series of functions, the rounding problem in Excel can basically be solved. The key is to distinguish when only the effect needs to be displayed and when the value needs to be changed.
