# linmap()

## Example

<figure><img src="/files/tf5XKjTI6uBKI9HGMsRr" alt=""><figcaption></figcaption></figure>

```python
  # value to be mapped from the first range
  x1 = round(min1+(max1-min1)*sin(frameCount/10)**2)
  line(x1, 25, x1, 75)
  text(str(x1), x1, 15)

  # mapping the value to the second range
  x2 = linmap(x1, min1, max1, min2, max2)
  text(str(round(x2,2)), x2, 285)
  line(x2, 225, x2, 275)
```

### Syntax

```
linmap(value, start1, stop1, start2, stop2, [withinBounds])
```

<table><thead><tr><th width="162">Input</th><th>Description</th></tr></thead><tbody><tr><td>value</td><td>the incoming value to be converted</td></tr><tr><td>start1</td><td>lower bound of the current range</td></tr><tr><td>stop1</td><td>higher bound of the current range</td></tr><tr><td>start2</td><td>lower bound of the newly mapped range</td></tr><tr><td>stop2</td><td>higher bound of the newly mapped range</td></tr><tr><td>withinBounds</td><td>boolean that specifies the behavior of the method if the mapped value is out of the bounds [start2, stop2]</td></tr></tbody></table>

### Description

**Maps** a value from one range to another, such that the **proportions are the same.**&#x20;

For example, number 2.5 is mapped from the range \[0, 10] to number 25 in the range \[0, 100]. Why? Because **in both cases, the value is fourth the distance away from the starting point of the range, and three fourths away from the ending point.**

Mapping 2.5 from the range \[0, 10] to the range \[10, 20] would give 12.5 for the same reason.

mapping 2.5 from the range \[0, 10] to the range \[10, 30] would give 15 for the same reason.

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://learnpython.strivemath.com/p5-python-web/reference/math/linmap.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.
