# LTE (<=)
URL: https://docs.valsight.ai/lte/
Description: Checking whether one input is less than or equal to another
**Category:** [Logical functions](/logical-functions/)

## Overview

The **LTE** function checks whether **the matching row on the first input is less than or equal to the matching row in the second input**; true (1) is returned, false (0) otherwise. Undefined values are treated as false (0).

Use this function when you need a 1/0 flag to mark where one input is less than or equal to another.

## Syntax

`LTE('Node1', 'Node2')`

`'Node1' <= 'Node2'`

## Parameters

| Parameter | Description                                                                         | Type           | Required |
| --------- | ----------------------------------------------------------------------------------- | -------------- | -------- |
| **Node1** | First input node, specified using the node name in single quotes (e.g. `'Profit'`). | Node reference | Yes      |
| **Node2** | Second input node.                                                                  | Node reference | Yes      |

## Example

### Checking whether one input is less than or equal to another

This example compares two input nodes row by row. The result returns 1 where the first input is less than or equal to the second and 0 otherwise.

**Input node:** `'A'`

| Year | Value |
| ---- | ----- |
| 2025 | 400   |
| 2026 | 700   |
| 2027 | 850   |
| 2028 | 500   |

**Input node:** `'B'`

| Year | Value |
| ---- | ----- |
| 2025 | 350   |
| 2026 | 400   |
| 2027 | 850   |
| 2028 | 600   |

**Formula:** `LTE('A', 'B')`

| Year | LTE Result |
| ---- | ---------- |
| 2025 | 0          |
| 2026 | 0          |
| 2027 | 1          |
| 2028 | 1          |
