#### Parameter types #### Parameter types
Each parameter has one of five different parameter types. A parameter's type impacts the kind of controls shown in the admin UI and also changes how the value is represented in code. Each parameter has one of five different parameter types. A parameter's type impacts the kind of controls shown in the admin UI and how it's represented in code.
| type name | code representation[^1] | UI control | Here's an overview over how the types are represented in the JSON payload returned from the Unleash server. The exact types will vary based on your programming language's type system.
|------------|-------------------------|--------------------------|
| string | `string` | A standard input field | :::note Unset values
| percentage | `int` between 0 and 100 | A value slider | Values of *all types* have an empty string (`""`) as the default value. As such, if you don't interact with a control or otherwise set a value, the value will be an empty string, regardless of the value's type.
| list | `string[]` | A multi-input text field | :::
| number | `int` | A numeric text field |
| boolean | `boolean` | An on/off toggle | | type name | code representation | example value | UI control |
|------------|----------------------------------------|---------------|--------------------------|
| string | `string` | `"a string"` | A standard input field |
| percentage | an `int` between 0 and 100 (inclusive) | `99` | A value slider |
| list | `string` (values are comma-separated) | `"one,two"` | A multi-input text field |
| number | `string` | `"123"` | A numeric text field |
| boolean | `"true"` or `"false"` | `"true"` | An on/off toggle |
