# Rounding Numbers

Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Rounding Numbers.

Excel provides a number of built-in worksheet functions for rounding numbers. The exact function you should use depends on exactly what you need to do with a value.

The first worksheet function is ROUND. This function allows you to essentially round to any power of ten. The syntax is as follows:

```=ROUND(num, digits)
```

The num argument is the number you want to round, while digits indicates how many digits you want the result rounded to. If digits is a positive value, then it represents the number of decimal places to use when rounding. Thus, if digits is 3, then num is rounded to three decimal places. If digits is zero, then ROUND returns a rounded whole number. If digits is a negative number, then ROUND returns a number rounded to the number of tens represented by digits. Thus, if digits is –2, then ROUND returns a number rounded to the nearest 100.

Two other worksheet functions that return rounded values are ROUNDUP and ROUNDDOWN. These functions use the same arguments as ROUND and behave virtually identically. The only difference is that ROUNDUP always rounds num up, meaning away from 0. ROUNDDOWN is the opposite, always rounding down, toward 0.

The second parameter in the Round function is simply the number of decimal places to the right of the decimal point that you want to round to. So 2 rounds to the nearest .01, 1 rounds to the nearest .01 , zero rounds to the nearest integer.

Following this sequence -1 rounds to the nearest 10, and -2 to the nearest 100; negative numbers bein the number of decimal place to the left of the decimal point.

=round(175,-1) -> 180
=round(174.99,-1) -> 170
=round(150,-2) -> 200
=round(149.99,-2) -> 100

What is concept behind rounding to negative numbers?
Like how i can calculate answer manualy for round(179,-1). I know excel will do it but how this formula works? I didn't understand the "rounded to nearest 100".

@Chuck,

If you want to round to only one decimal place but show two decimal places then you can use either:

1. use =ROUND(4.33,1) and format the cell to show 2 decimal places, or

2. use the formula =ROUND(4.33,1) & "0" in this case the result will be text (the result can still be used in formulas as Excel will convert this to a number for calculation purposes - it does in Excel 2010 anyway).

Chuck: You do it just as explained in this tip. If the number (4.33 or 4.39) is in cell A1, then you use the following:

=ROUND(A1, 2)
