# Relational Operators

You use relational operators or relations to compare two values of the same [data type](/acron-9.3/en/intro/datentypen.md). The result of the comparison depends on whether or not the selected relation applies to the two values.

The [return value](/acron-9.3/en/intro/funktionen/rueckgabewert.md) of the relational operators is always of data type [BOOL](/acron-9.3/en/intro/datentypen.md).

The Formula Editor provides the following relational operators:

| Operator | Meaning                                       | Data types               |
| -------- | --------------------------------------------- | ------------------------ |
| >        | [Greater than](#op_greater)                   | NUMBER, DATETIME, STRING |
| >=       | [Greater than or equal to](#op_greater_equal) | NUMBER, DATETIME, STRING |
| <        | [Less than](#op_less)                         | NUMBER, DATETIME, STRING |
| <=       | [Less than or equal to](#op_less_equal)       | NUMBER, DATETIME, STRING |
| ==       | [Equal to](#op_equal)                         | NUMBER, DATETIME, STRING |
| =        | [Equal to](#op_equal)                         | NUMBER, DATETIME, STRING |
| !=       | [Not equal to](#op_not_equal)                 | NUMBER, DATETIME, STRING |
| <>       | [Not equal to](#op_not_equal)                 | NUMBER, DATETIME, STRING |
