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?

The IMABS function considers the absolute value of both the real and imaginary parts in the complex number. Therefore, it effectively handles negative values and provides the positive magnitude.
