For each user question, use the appropriate tool to retrieve the necessary information from the Dynamic product documentation's vector database.\n\n**Mandatory rules:**\n\n1. **Single source of truth:** Your answer MUST be entirely and solely derived from the information present in the provided documentation.\n2. **Accuracy and implicit citation:** Base your answer as literally as possible on the documentation text. Rephrase for clarity and conciseness, but do not add any information not found there. Act as if the documentation is your only knowledge in the world.\n3. **Do not mention the process:** Never mention your tool or the fact that you are a RAG system in your answer to the user.

"output": "To calculate a surface or area, you can use a field formula. This allows you to assign a value to a field based on the values of other fields, such as width and height.\n\n### Basic Calculation\n\nYou can calculate the area of a rectangle by creating a \"Dynamic Variable\" field (e.g., named `area`) and applying the following formula:\n\n\n```js\n[area] = [width] * [height]\n```\n\n\n### Using the Calculated Area\n\nOnce you have the `[area]` field, you can use it in other formulas or conditions.\n\n* **In other formulas:** For example, to calculate a price based on the area:\n \n```js\n [area] * 10\n ```\n\n\n* **In conditions:** To apply logic based on the area:\n \n```js\n [area] > 100\n ```\n\n\n### Advanced Examples\n\nYou can also incorporate formula functions for more complex logic directly within your price or weight formulas.\n\n* **Round up to the nearest whole square meter:**\n \n```js\n ROUNDUP([width] * [height] / 10000) * 10\n ```\n\n\n* **Charge for at least 1 square meter:**\n \n```js\n MAX([width] * [height] / 10000, 1) * 10\n ```\n\n\n* **Charge a minimum price:**\n \n```js\n MAX([width] * [height] / 10000 * 10, 50)\n ```"

The result from this formula is added to the base product weight configured in PrestaShop.\n\n### Weight Formula\n\nYou can define a formula to calculate the weight. For example, to charge 2kg for each square meter, the formula would be:\n\n\n```js\n[width] * [height] / 10000 * 2\n```\n\n\nAdditionally, you have the option to show the calculated weight on the product page by enabling the **Display weight to customers** setting for the product.\n\n### Weight Calculation Using PHP\n\nFor more complex calculations, you can use a PHP file placed in the `/calculator` folder. This method is similar to PHP price calculation with two main differences:\n\n* The variable that must be assigned is `$weight`.\n* The file must be named `weights.php` to apply to all products, or `weightX.php` to target a specific product with ID `X`."
