+#### <a id="beautify-number"></a> beautifyNumber()
+
+```ts
+beautifyNumber(value: number, options: IBeautifyNumberOptions);
+```
+
+Produces a formatted string that was created out of the number provided as an input of the function.
+Formatting rules:
+
+- splits a whole part of a number by thousands
+- adds a `joint` symbol between thousands
+- adds a `delimiter` symbol between a whole and a floating part
+
+#### Options
+
+| Name    | Type                     | Required | Default value                    |
+| ------- | ------------------------ | -------- | -------------------------------- |
+| value   | `number`                 | +        | -                                |
+| options | `IBeautifyNumberOptions` | -        | `{ delimiter: '.', joint: ' ' }` |
+
+Examples:
+
+```ts
+// Whole numbers
+const result = beautifyNumber(1000); -> '1 000'
+const result = beautifyNumber(1_000); -> '1 000'
+
+// With floating point
+const result = beautifyNumber(1000.123); -> '1 000.123'
+const result = beautifyNumber(1000.123, { delimiter: ',' }); -> '1 000,123'
+const result = beautifyNumber(1000.123, { delimiter: ',', joint: '_' }); -> '1_000,123'
+
+// Throws error
+const result = beautifyNumber(1000.123, { delimiter: ',', joint: ',' }); -> [Error: Please provide different delimiter and joint values]
