# ROUND

The ROUND function is used to round a number to a specified number of digits. It is commonly employed in financial modeling, data analysis, and mathematical calculations to simplify values and improve readability.

## Syntax ðŸ”—

=ROUND(`number`

, `num_digits`

)

`number` | The number you want to round. |

`num_digits` | The number of digits to which you want to round the given number. |

## About ROUND ðŸ”—

When you need to tidy up numbers in Excel, the ROUND function comes to the rescue. Whether you're dealing with financial figures, statistical data, or simply want to present values in a clearer format, ROUND offers a straightforward solution for rounding numbers to a specific level of precision. This function proves handy in scenarios where a precise result is secondary to a rounded approximation with a defined number of decimal places or significant figures. By specifying the number of digits, you can control the level of precision to which the number is rounded, aiding in better visualization and interpretation of data analysis outcomes.

## Examples ðŸ”—

Suppose you have the number 15.6789 and you want to round it to 2 decimal places. The ROUND formula would be: =ROUND(15.6789, 2) This will return 15.68.

If you have the number 1234 and you wish to round it to the nearest hundred, you can use: =ROUND(1234, -2) This will result in 1200.

## Notes ðŸ”—

The ROUND function follows standard rounding rules. When the digit to be rounded is exactly halfway between two numbers, it rounds to the nearest even number (known as 'round half to even' or 'bankers' rounding'). If the number of digits is negative, rounding occurs to the left of the decimal point. Always ensure the number of digits specified aligns with your desired level of precision when using the ROUND function.

## Questions ðŸ”—

**How does the ROUND function handle rounding for numbers with fractional parts?**

The ROUND function rounds numbers with fractional parts according to standard rounding rules, where digits 0-4 are rounded down and digits 5-9 are rounded up. If the digit following the specified number of digits is 5, rounding is performed to the nearest even number.

**Can the ROUND function round numbers to a specific number of decimal places?**

Yes, you can specify the number of decimal places to which you want to round a number using the `num_digits`

argument in the ROUND function. This allows you to control the precision of the rounding operation.

**What happens if the number of digits specified in the ROUND function is greater than the actual number of decimal places in the number being rounded?**

If the `num_digits`

value in the ROUND function exceeds the number of decimal places in the number being rounded, Excel pads the result with zeroes to match the specified precision. For instance, rounding 5 to 3 decimal places using =ROUND(5, 3) will yield 5.000.
