The Excel IMREAL function returns the real coefficient of a complex number in the form x + yi or x + yj
Syntax:= =IMREAL (inumber)
The IMREAL function syntax has the following arguments:
- Inumber: Required. A complex number for which you want the real coefficient
Example: Let’s look at some Excel IMREAL function examples and explore how to use the IMREAL function as a worksheet function in Microsoft Excel:
Based on the Excel spreadsheet above, the following IMREAL examples would return:
- Complex Numbers in Excel are simply stored as text.
- When a text string in the format “a + bi” or “a + bj” is supplied to one of Excel’s built-in Complex Number Functions, this is interpreted as a complex number.
- The complex number functions can accept a simple numeric value, as this is equivalent to a complex number whose imaginary coefficient is equal to 0.
- Use COMPLEX to convert real and imaginary coefficients into a complex number.
- If inumber is not recognized as a complex number, IMREAL returns the #NUM! error.
- If inumber is a logical value, IMREAL returns the #VALUE! error.
