When using IMREAL, common questions usually involve parameter format, unexpected results, and batch fill. This section includes 3 frequent questions and a short glossary.
FAQ
How do I check an IMREAL error value?
- Check whether the parameter uses a valid complex-number text format, such as
3+5ior4j. - Make sure the formula uses standard half-width parentheses, commas, and characters.
- If the parameter comes from another cell, check whether that cell contains extra spaces or nonnumeric characters.
Why does the IMREAL result not match what I expected?
- Confirm that the input is complex-number text rather than plain descriptive text.
- Check whether the referenced cell has been changed to another value or format.
- Reopen the function arguments window and verify the current parameter content again.
How do I use IMREAL in multiple cells?
- Enter a correct IMREAL formula in the first target cell.
- Move the pointer to the fill handle at the lower-right corner of the cell.
- Drag downward or sideways to copy the formula to other cells.
