# Math

Math blocks provide numerical operations and calculations for your scripts. Use these blocks to perform arithmetic, apply mathematical functions, and manipulate numeric values from sensors or variables.

## value

<div align="left"><figure><img src="/files/ExGtOpZ6GvTmsOoRLSBs" alt=""><figcaption></figcaption></figure></div>

A numeric constant. Use this block to provide fixed numbers for calculations, comparisons, or as parameters to other blocks.

**Parameters:**

* **Value** (Number): Enter any numeric value (integers or decimals)

**Example:**

<figure><img src="/files/l4Kn7BZaE405OunkGJbO" alt=""><figcaption><p>Define temperature thresholds</p></figcaption></figure>

## math operation

<div align="left"><figure><img src="/files/B8LxoUw8AyBNNQUY1JpR" alt=""><figcaption></figcaption></figure></div>

Applies a single-value mathematical operation. Choose from absolute value (removes sign) or negation (flips positive to negative and vice versa).

**Parameters:**

* **Operation**: Select `abs` (absolute value) or `-` (negate)
* **Value** (Number): The number to operate on

**Returns:**

* **Number**: The result of the operation

**Example:**

<figure><img src="/files/f85NMRimfZFXRacWc7DI" alt=""><figcaption><p>Temperature difference calculation</p></figcaption></figure>

## arithmetic

<div align="left"><figure><img src="/files/ifF8Jo1IIq2vUCJDAGcY" alt=""><figcaption></figcaption></figure></div>

Performs basic arithmetic operations between two numbers.

**Parameters:**

* **Left Value** (Number): The first number
* **Operator**: Choose `+` (add), `-` (subtract), `×` (multiply), `÷` (divide), `^` (power)
* **Right Value** (Number): The second number

**Returns:**

* **Number**: The result of the calculation

**Example:**

<figure><img src="/files/bhqwIKcldGbSNsIzlPRN" alt=""><figcaption><p>Convert raw sensor value to voltage</p></figcaption></figure>

## number condition

<div align="left"><figure><img src="/files/J3gQY75vahgepeCqSJI5" alt=""><figcaption></figcaption></figure></div>

Checks whether a number meets a specific condition. Use this for pattern detection or periodic actions.

**Parameters:**

* **Value** (Number): The number to check
* **Condition**: Select `even`, `odd`, `positive`, `negative`, `whole`, `divisible by`

**Returns:**

* **Boolean**: `#t` (true) if the condition is met, `()` (false) otherwise

**Example:**

<figure><img src="/files/iWnHCXqjKI3BYkvG892e" alt=""><figcaption><p>Read sensor value every 5th script execution</p></figcaption></figure>

## remainder

<div align="left"><figure><img src="/files/EALKl4Hzy8KVtjAx0C2h" alt=""><figcaption></figcaption></figure></div>

Calculates the remainder after dividing one number by another (modulo operation). Useful for creating repeating patterns or detecting multiples.

**Parameters:**

* **Dividend** (Number): The number to be divided
* **Divisor** (Number): The number to divide by

**Returns:**

* **Number**: The remainder of the division

**Example:**

# Agent Instructions: Querying This Documentation

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.uniot.io/platform/sandbox/visual-editor/math.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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
