# SQRT

The SQRT function returns the square root of a number.

## Syntax ðŸ”—

=SQRT(`number`

)

`number` | The number for which you want to calculate the square root. |

## About SQRT ðŸ”—

When you need to quickly find the square root of a number in Excel, the SQRT function comes to the rescue. It simplifies the process of calculating square roots, eliminating the need for manual calculations and providing a precise result in no time. Whether you are working on mathematical calculations, engineering projects, or statistical analysis, SQRT offers a convenient solution for determining the square root of any given number with ease and accuracy.

## Examples ðŸ”—

If you want to find the square root of 25 using the SQRT function, you simply enter the formula in a cell as follows: =SQRT(25)

To calculate the square root of a cell reference containing a number, such as A1, you can use: =SQRT(A1)

## Notes ðŸ”—

The SQRT function only returns the principal (positive) square root of a number. If you provide a negative number as input, SQRT will return a #NUM! error because the square root of a negative number is a complex number in mathematics, which Excel does not support in the SQRT function.

## Questions ðŸ”—

**What happens if I provide a negative number as input to the SQRT function?**

If you provide a negative number as input to the SQRT function, Excel will return a #NUM! error. This is because the square root of a negative number results in a complex number, which Excel does not support in the SQRT function.

**Can I use the SQRT function to calculate square roots of decimal numbers?**

Yes, the SQRT function can handle decimal numbers as input. It will calculate the square root of the decimal number provided and return the result accordingly.

**Is there a limit to the size of the number that can be used with the SQRT function?**

The SQRT function in Excel can handle a wide range of numerical inputs, including very large numbers. However, extremely large or small numbers may result in scientific notation being displayed as the output in Excel.
