The Float class wraps a value of the primitive type float in an object. An object of type Float contains a single field whose type is float.
Float data type is a single-precision 32-bit IEEE 754 floating point.
Float is mainly used to save memory in large arrays of floating point numbers.
Default value is 0.0f.
Float data type is never used for precise values such as currency.
Example: float myFloat = 234.5f
1. In the MainActivity.java file, add the below to the onCreate method. This will create a Float variable named myFloat.
float myFloat;
2. Compile and run!
