The IMREAL function in Google Sheets is designed to extract the real coefficient from a complex number. This can be particularly useful in mathematical, engineering, and scientific applications where complex numbers are involved. By utilizing this function, users can easily isolate the real part for further calculations or analyses.

Syntax

IMREAL(complex_number)

• complex_number: The complex number from which you want to extract the real part. It can be in the form of a text string (e.g., “3 + 2i”) or a reference to a cell containing such a string.

Example #1

=IMREAL("3 + 4i")

This function would extract the real part of the complex number, resulting in 3.

Example #2

=IMREAL(A1)

If cell A1 contains the value “5 – 3i”, this function will return 5 as the real coefficient.

Example #3

=IMREAL("-2.5 + 0i")

For this complex number, the function will yield -2.5 as the real part.

Error handling

• VALUE!: This error occurs when the input provided is not a valid complex number format. Ensure that the complex number is correctly entered as a string.
• NAME?: This error indicates that the function name is not recognized, possibly due to a typo. Double-check the function spelling and that you have an active Google Sheets environment.
• NUM!: This error is displayed if the input is a number but not a valid complex number. Check that the correct complex number syntax is being used.

Conclusion

In conclusion, the IMREAL function in Google Sheets is a powerful tool for users dealing with complex numbers. By easily isolating the real part, it enhances productivity in mathematical operations and analytical tasks. Whether for academic or professional purposes, understanding how to use the IMREAL function can significantly streamline your data processing tasks.
