## Error values when using formulas

If you enter a formula and Calc is not able to interpret it, it will display an error in the cell. The main errors that you will come across are shown below.

Error message | Cause of error |
---|---|

#NAME | An identifier could not be evaluated. This usually means that the reference to a cell or row or column was invalid. This is also known as error 525 |

#VALUE | Calc was unable to evaluate one of the cell references in the formula as a number. This error usually occurs when one of the cells referenced in a formula contains text rather than a number. This is also known as error 519. |

#REF | This indicates that the formula contains a reference to a cell, row or column that was deleted. It is also known as error 524. |

Invalid floating
point operation |
A formula contains division by zero. A common misunderstanding is that because multiplication by zero results in zero, so does division by zero. Division by zero is however impossible. This is also known as error 503. |
