# Float {% tabs %} {% tab title="Swift" %} `Float` is a single-precision 4 byte floating-point type with an approximate range of 1.2E-38 to 3.4E+38. The default value of a `Float` is 0.0. You can change the default value of the property by assigning a new value in an overridden [`reset`](https://www.electricbolt.co.nz/api/Classes/APLConfiguration.html#/c:objc\(cs\)APLConfiguration\(im\)reset) method. {% endtab %} {% tab title="Objective-C" %} `float` is a single-precision 4 byte floating-point type with an approximate range of 1.2E-38 to 3.4E+38.

You can change the default value of the property by assigning a new value in an overridden [`reset`](https://www.electricbolt.co.nz/api/Classes/APLConfiguration.html#/c:objc\(cs\)APLConfiguration\(im\)reset) method. `float` properties should be declared in your [`APLConfiguration`](https://www.electricbolt.co.nz/api/Classes/APLConfiguration.html) subclass header file as follows: ```objectivec @import AppfigurateLibrary; @interface Configuration : APLConfiguration @property(nonatomic, assign) float propertyName; ... ``` {% endtab %} {% tab title="Dart" %} The flutter [`APLNativeConfiguration`](https://pub.dev/documentation/appfigurateflutter/latest/appfigurateflutter/APLNativeConfiguration-class.html) class defers to the underlying platform [`APLConfiguration`](https://www.electricbolt.co.nz/api/Classes/APLConfiguration.html) (iOS) or [`nz.co.electricbolt.appfiguratelibrary.Configuration`](https://www.electricbolt.co.nz/api/android/nz/co/electricbolt/appfiguratelibrary/Configuration.html) (Android) subclass to read property values. As Dart doesn't have a single-precision `float` data type, you should map to a double-precision `double` data type instead: | Dart property type | Swift property type | Objective-C property type | Kotlin property type | Java property type | | ------------------ | ------------------- | ------------------------- | -------------------- | ------------------ | | **double** | Float | float | Float | float | | {% endtab %} | | | | | {% tab title="JavaScript" %} The React Native module `AppfigurateModule` class defers to the underlying platform [`APLConfiguration`](https://www.electricbolt.co.nz/api/Classes/APLConfiguration.html) (iOS) or [`nz.co.electricbolt.appfiguratelibrary.Configuration`](https://www.electricbolt.co.nz/api/android/nz/co/electricbolt/appfiguratelibrary/Configuration.html) (Android) subclass to read property values.
