Key Takeaways
- The SIGN function returns:
- 1 for positive numbers
- 0 for zero
- -1 for negative numbers
- Issues with this function often stem from input types, formatting, or errors in the formula.
Common Solutions
1. Check Your Formula Syntax
Ensure that your syntax is correct:
- Format:
=SIGN(number) - Example:
=SIGN(A1)where A1 contains the number you want to evaluate.
2. Confirm Input Data Type
Make sure the cell contains a number, not text or an empty value:
- Right-click on the cell > Format Cells > Number.
- If it’s formatted as text, change it to Number to see if it solves the issue.
3. Remove Extra Spaces
Remove any leading or trailing spaces in the cell:
- Use the
TRIMfunction:=SIGN(TRIM(A1)).
4. Check for Errors
Make sure the cell does not contain an error:
- If there’s an error, Excel may not compute the function correctly.
- Fix the underlying error first.
5. Use the Evaluate Formula Tool
To see how Excel evaluates your formula:
- Go to the Formula tab > Click on ‘Evaluate Formula’.
- This will help you identify where the issue lies.
Rare Solutions

- Go to Control Panel > Programs > Uninstall a program.
