How to remove a comma in the Xiaomi calculator and replace it with a point: the complete guide

The problem with showing a comma instead of a point in the Xiaomi calculator is familiar to many users of smartphones on MIUI. Instead of the usual number format (for example, 3.14), the device persistently shows 3.14, which is not only annoying, but also complicates work with financial calculations, engineering formulas or programming, the reason for this is the regional settings of the system, which automatically adjust to the user’s locale.

In most European countries (including Russia), the fractional partition is traditionally used as a comma, while technical standards and programming adopt a dot. Xiaomi, following the logic of Android, inherits these settings from the system language package. Fortunately, there are several ways to fix the situation, from changing language parameters to installing alternative calculators. In this article, we will analyze all current methods, including hidden MIUI settings, which are not obvious even to advanced users.

It is important to understand that the problem is not related to the hardware of the smartphone – it is purely a software nuance. Therefore, all the proposed solutions are safe and do not require superuser rights (root). However, some methods can reset other regional parameters (for example, the format of the date or currency), so before changing it, it is worth weighing the pros and cons.

Why is Xiaomi calculator comma instead of a dot?

The root of the problem lies in the localization system settings that Xiaomi takes from standard Android functionality, and here are the key reasons for this behavior:

• 🌍 Regional standards: In Russia, Europe and most CIS countries, it is customary to use a comma as a fractional part divider (for example, 1.5 kg), whereas in the USA, UK and technical documentation, a point (1.5 lbs) is used. Android automatically adjusts to the selected locale.
• 📱 Settings MIUI: Xiaomi firmware further imposes its rules for formatting numbers, which may conflict with the expectations of users accustomed to the “technical” standard.
• 🔄 System updates: After major updates MIUI (For example, switching from version 12 to version 13 may reset localization settings to default values, returning the comma even if it was previously removed.

Interestingly, the problem is not only with the standard Xiaomi calculator, but also with many third-party applications that inherit the system settings for formatting numbers, such as Google Calculator or Microsoft Math Solver, which can also display a comma if you do not adjust the system settings.

Another nuance: on some models (for example, the Redmi Note 10 Pro or POCO X3 Pro), the comma appears only in the portrait mode of the calculator, while in the landscape mode the dot is displayed, which is due to the fact that in the extended form the application uses a scientific format of numbers, where the separator is fixed.

Method 1: Change the language of the system to English (USA)

The most reliable and versatile method is to change the system language to English (USA), which is the default region that uses the dot as a separator, and the change will affect all applications, including the calculator.

Step instructions:

1. Open Settings → Additional → Language and input.
2. Select the language (first item in the list).
3. Scroll down and find English (United States).If it's not on the list, click Add Language and select it.
4. Confirm the change and restart the smartphone (required!).

After rebooting, check the calculator - the divider should change to a point. If the interface language is uncomfortable for you, you can return Russian, but leave the English locale for numbers (more about this in the next way).

Take screenshots of current settings

Remember passwords from accounts (may be required again)

Check for important notifications (they will be in English)

Connect the smartphone to charging (in case of a long reboot)-->

Warning: The change of language will affect all system applications, including Messages, Contacts and Phone.Some labels (e.g., in banking apps) may appear in English even if you return Russian as your primary language later.

Method 2: Configure regional number format without changing the language

If you don't want to switch to the English interface, you can only change the format of numbers, leaving the Russian language.

Step 1: Install English (USA) as a second language (not a primary language!):

1. Go to Settings → Additional → Language and Input → Language.
2. Click Add Language and select English (United States).
3. Drag English to second place on the list (under Russian).

Step 2: Change your regional settings:

1. In the same menu (Language and input), select Additional → Regional Preferences.
2. Set the region on the US or the UK.
3. Reset the device.

This method doesn't work on all versions of MIUI, but it often helps keep the Russian interface in the technical format of numbers. If you have a comma left after the reboot, try making English the primary language temporarily, then returning Russian - sometimes this resets the cache of settings.

Method 3: Use of alternative calculators

If the system settings don't help or you don't want to change them, it's easier to install a third-party calculator with a forced dot.

• 📊 Google Calculator: Minimalist, science mode, most of the time, ignores system settings and always uses a dot.
• 🧮 CalcES: Engineered calculator with customizable separator (you can choose a point manually in the settings).
• 💰 Financial Calculator: Optimized for financial calculations, always showing numbers in the format of 1000.00 (dot for fractional part).
• 📱 RealCalc Scientific Calculator: Allows you to manually set the format of displaying numbers in settings (Settings) → Display → Decimal separator).

To establish any of them:

1. Open the Play Market and find the app by name.
2. Install and open it.
3. In most calculators, the number format is configured in the Settings → Number format menu.

Tip: Check reviews before you install -- some calculators may contain ads or collect data -- and Google and Microsoft's apps are the most reliable.

💡

If you want a calculator with a history of computation, try ClevCalc. It not only saves all operations, but also allows you to export them to a text file.

Method 4: Editing system files (for advanced users)

If previous methods have failed, you can manually edit the system files that format numbers, which requires root rights or access through ADB, so it is only suitable for advanced users.

Instructions via ADB (without root):

1. Install Platform Tools on your PC and connect your smartphone via USB (enable USB Debugging in the developer settings).
2. Adb shell settings put system locales en_US
3. Reset the device.

For users with root rights:

1. Install a file manager with root support (such as Root Explorer).
2. Go to /system/csc/ and find the others.xml file.
3. Open the file and find the line with the DecimalSeparator parameter. Change the value of, to..
4. Save the changes, set the rights to 644 and restart the smartphone.

⚠️ Warning: Incorrect editing of system files can lead to bootloop ( looped reboot) or reset settings. Before making changes, back up through TWRP or MIUI Backup.

This method is the most radical, but also the most effective – it is guaranteed to change the separator in all applications, including banking and system utilities.

Method 5: Resetting calculator settings to factory

Sometimes a comma appears due to a failure in the settings of the Calculator application itself, in which case the reset of its data will help:

1. Go to Settings → Applications → Application Management.
2. Find the Calculator (or com.miui.calculator) in the list.
3. Select Warehouse → Clear data and Clear cache.
4. Restart the app.

After resetting, the calculator will return to factory settings, which may differ from the current system settings. If this method works, fix the result by changing the language settings (see Method 1 or Method 2).

⚠️ Attention: Clearing the calculator data will delete its computation history. If you need one, pre-take screenshots or export the data (if the application supports this feature).

Comparison of methods: which one to choose?

To make the choice easier, we have compiled a table with the pros and cons of each method:

For most users, the best solution would be Method 1 (change language) or Method 3 (install an alternative calculator).If you're ready to experiment and have a backup of the data, you can try Method 4 for global fixing.

💡

The most universal method is the change of language to English (USA), which works on all versions of MIUI and does not require additional programs.

Frequent Mistakes and How to Avoid Them

When trying to remove a comma, users often face typical problems, and here's how to prevent them:

• 🔄 The comma returns after the update MIUI: This is because of the reset of regional settings, so the solution is to repeat Method 1 or Method 2 after the update. To avoid the problem, turn off the automatic firmware update in Settings. → The phone. → Updating the system.
• 📱 Not all applications change format: Some programs (such as 1C or Excel) have their own number formatting settings.
• ⚠️ The smartphone stopped turning on after editing system files: This means you changed the critical parameter. The solution is to reset the settings via Fastboot or restore the backup. TWRP.
• 🌐 In some applications, a dot, in others a comma: This is normal if you use Method 3 (a third-party calculator). MIUI, And outsiders to their own.

If you have a comma left after all the manipulations, check your Xiaomi account settings: sometimes the cloud profile override local settings. Go to Settings → Xiaomi Account → Synchronization and temporarily disable the synchronization of settings.
