44. Use COMPLEX inside a nested formulaFree

How-to Guide

1. Enter the COMPLEX function

Entry path: Formula tab → formula bar

  1. Open WPS Spreadsheet and select the target cell.
  2. Type = to start formula entry.
  3. Type COMPLEX(.
  4. Review the function hint and prepare to enter the arguments.

Success Criteria

  • Interface result: =COMPLEX( appears in the cell or formula bar.
  • You can continue: You can enter arguments and complete the formula.

Tips While Using

  • Common mistake: If you do not start with =, the content may be treated as plain text.

2. Fill in the real and imaginary parameters

Entry path: Select a cell and type directly in the formula bar

  1. After COMPLEX(, enter the real-part argument.
  2. Type a comma and enter the imaginary-part argument.
  3. Add the suffix argument if needed.
  4. Press Enter to confirm the formula.

Success Criteria

  • Interface result: The cell returns a complex-number text result.
  • You can continue: You can copy the formula or edit the arguments again.

Tips While Using

  • Common mistake: An unclosed parenthesis or incomplete separators can cause a formula error.

3. Use cell references to build a complex result

Entry path: Formula bar

  1. Put the real part and imaginary part in separate cells.
  2. Select the result cell and type =COMPLEX(.
  3. Reference the real-part cell and the imaginary-part cell in order.
  4. Press Enter to generate the result.

Success Criteria

  • Interface result: The result cell shows a complex number built from the referenced values.
  • You can continue: When the source cells change, the result updates automatically.

Tips While Using

  • Common mistake: Referencing the wrong cells can produce an unexpected result.

4. Use COMPLEX inside a nested formula

Entry path: Formula bar

  1. Select the cell where you want the result.
  2. Type a combined formula that includes COMPLEX.
  3. Complete the remaining arguments or outer function based on the formula hint.
  4. Press Enter to view the result.

Success Criteria

  • Interface result: The cell returns the completed calculation result.
  • You can continue: You can copy, fill, or adjust the outer formula.

Tips While Using

  • Common mistake: In deeper nested formulas, check parentheses and argument order carefully.
