This FAQ covers 3 common question types about TANH in WPS, including errors, unexpected results, and filling formulas across cells, plus a short glossary.
FAQ
What should I do if TANH shows an error after I enter it?
- Check whether the parameter is a valid numeric value instead of plain text or text with extra spaces.
- Check whether the formula format is complete, including the initial
=sign and matching parentheses. - If the parameter comes from another cell, confirm that the referenced cell contains data that can be used in a numeric calculation.
Why does the TANH result look different from what I expected?
- Confirm that the input value is correct, especially if the formula references another cell.
- Check the cell format and original data so numbers are not stored as text.
- If needed, reopen the function description and verify the
TANH(number)parameter requirement.
How do I use TANH in multiple cells at once?
- Enter the correct TANH formula in the first target cell.
- Select that cell and move the pointer to the fill handle in the lower-right corner.
- Drag the fill handle down or across to copy the formula to other cells, then review whether the references behave as expected.
