# IMABS

The IMABS function is used to return the absolute value (magnitude) of a complex number in the form of x + yi.

## Syntax

=IMABS(`Inumber`

)

`Inumber` | The complex number for which you want to find the absolute value (magnitude). |

## About IMABS

When dealing with complex numbers in Excel, the IMABS function comes to the rescue by providing a straightforward way to determine the absolute value of a complex number. In the realm of mathematics and engineering, complex numbers often play a vital role, notably in scenarios involving electrical engineering, signal processing, and more. With IMABS, you can effortlessly calculate the magnitude of a complex number in the format x + yi, aiding in various computations where the absolute value is required for further analysis and problem-solving.

## Examples

Suppose you have a complex number 3 + 4i. You want to find the absolute value of this complex number. The IMABS formula would be: =IMABS(3+4i)

Consider another complex number -2 + 6i. You seek to determine its absolute value. Using IMABS, the calculation would be: =IMABS(-2+6i)

## Questions

**What does the IMABS function return?**

The IMABS function returns the absolute value (magnitude) of a complex number in the form x + yi.

**Can I use the IMABS function for real numbers?**

No, the IMABS function is specifically designed to work with complex numbers and will return an error if used with real numbers.

**How does the IMABS function handle negative values in complex numbers?**
