The general calculator is familiar to every Android user, but what many don't know is that the calculator on the Xiaomi smartphone adds more functions when we rotate the device horizontally, where functions such as sine, cosine, tangent, root calculus or the constant Pi become visible.

Note: The rotation lock must be deactivated on the device.

On devices that come with the App Mi Calculator, just tap the button in the lower left corner to enable or disable the additional features.
