# Logical Operators

These operators are widely used in Formulas. For example, in an IF formula, you can use = to check whether one variable is equal to another or to a constant value and take an action based on this, or you can use > to check whether one value is greater than another.

* **`=` Equal to:** This operator checks whether two values are equal. If the values are equal, it returns true; otherwise, it returns false.
* **`<>` Not equal to:** This operator checks whether two values are different. If the values are different, it returns true; otherwise, it returns false.
* Operators used for Numerical Comparisons:
  * **`>=` Greater than or equal to:** checks that the value on the left is greater than or equal to the value on the right
  * **`>` Greater than:** checks that the value on the left is strictly greater than the value on the right
  * **`<=` Less than or equal to:** checks if the value on the left is less than or equal to the value on the right
  * **`<` Less than:** checks if the value on the left is strictly less than the value on the right.
