# Currency

The application's currency format can be customized for each language by modifying the `lang.json` files located in the `gksphone/config/locales` directory.

## Step 1: Locate the Language Files

* Navigate to the `gksphone/config/locales` directory.
* Each language has its own JSON file (e.g., `en.json` for English, `de.json` for German).

## **Step 2: Update the `PHONE_SETTINGS_NUMBERFORMAT` Setting**

In each language file, there is a key named `PHONE_SETTINGS_NUMBERFORMAT` that determines the number format and currency for that language.

Example Format:

```json
"PHONE_SETTINGS_NUMBERFORMAT": "en-US",
```

This specifies the `en-US` locale, which uses the dollar symbol (`$`) for currency.

## **Step 3: Define the Currency Format for Each Language**

Here are some examples of common locale codes and their corresponding currencies:

| Locale Code | Currency Symbol     |
| ----------- | ------------------- |
| `en-US`     | `$` (US Dollar)     |
| `de-DE`     | `€` (Euro)          |
| `en-GB`     | `£` (British Pound) |
| `fr-FR`     | `€` (Euro)          |
| `ja-JP`     | `¥` (Japanese Yen)  |
| `tr-TR`     | `₺` (Turkish Lira)  |

**Update the `PHONE_SETTINGS_NUMBERFORMAT` in each file based on the desired currency.**

**Search for `"APP_CURRENCY"` in the language file and change the currencies in that section to your liking**

You need to restart the phone for the changes to take effect.

## 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, and the optional `goal` query parameter:

```
GET https://docs.gkshop.org/gksphone-v2/configuration/currency.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
