# Logical Operators Section

## Logical Operator Nodes

This section encompasses all nodes for logical comparisons between values. There are three major logical operators in Blup:

1. **AND**: Returns true if both provided values are true. For example: `X<5 AND X<10`.
2. **OR**: Returns true if any of the provided values is true. For example: `X<40 OR X<50`.
3. **NOT**: Inverts the provided value. For example, if true is provided, it returns false and vice versa.

## AND Node

This node facilitates the implementation of logical AND between two boolean values. It returns true only if both provided values are true; otherwise, it returns false.

### Components of Node

| Component           | Description                                                                                          |
| ------------------- | ---------------------------------------------------------------------------------------------------- |
| **A**               | Input node point for the first boolean value.                                                        |
| **B**               | Input node point for the second boolean value.                                                       |
| **Use Run Trigger** | Checkbox to add a run function node point to the node. Checking this box displays the function node. |

## OR Node

This node implements logical OR between two boolean values. It returns true if either A or B is true; otherwise, it returns false.

| **B**               | Input node point for the second boolean value.                                                       |
| **Use Run Trigger** | Checkbox to add a run function node point to the node. Checking this box displays the function node. |
| **A OR B**          | Output node providing the result.                                                                    |

## NOT Node

This node applies logical NOT to a provided boolean value. It negates the provided value, returning true if the provided value is false, and false if it is true.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.blup.in/wiki/logics/logical-operators-section.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
