 [//]: # (title: Unsigned integer types)
 
-In addition to [integer types](numbers.md#integer-types), Kotlin provides the following types for unsigned integer numbers:
+* types | unsigned integer numbers
 
-| Type     | Size (bits) | Min value | Max value                                       |
-|----------|-------------|-----------|-------------------------------------------------|
-| `UByte`  | 8           | 0         | 255                                             |
-| `UShort` | 16          | 0         | 65,535                                          |
-| `UInt`   | 32          | 0         | 4,294,967,295 (2<sup>32</sup> - 1)              |

+    * supported operations | number types == (MOSTLY)  supported operations | unsigned number types
 
-Unsigned types support most of the operations of their signed counterparts.
-
-> Unsigned numbers are implemented as [inline classes](inline-classes.md) with a single storage property that contains the corresponding 
-> signed counterpart type of the same width. If you want to convert between unsigned and signed integer types, 
-> make sure you update your code so that any function calls and operations support the new type.

 ## Unsigned arrays and ranges
 
+* TODO:
 > Unsigned arrays and operations on them are in [Beta](components-stability.md). They can be changed incompatibly at any time.
