Java float data type

In Java, the float data type is a single-precision, 32-bit floating-point data type that represents decimal values with a range of approximately 1.4E-45 to 3.4E+38.

Here's an example of how to declare and use a float variable in Java:

public class Main {
  public static void main(String[] args) {
    float value = 3.14f;  // The "f" suffix indicates that the value is a float
    System.out.println(value);  // prints "3.14"
  }
}

The float data type is smaller and less precise than the double data type, which is a double-precision, 64-bit floating-point data type. In general, it is recommended to use the double data type for decimal values unless you have a specific reason to use the float data type, such as to save memory or to match the precision of an external system.
