What is float in Java?

In java, Float is primitive data type having number with a decimal point. It contains number of fractional parts from 3.4e−038 to 3.4e+038. Note that you should end the value with an “f”.

There are two types of primitive floating point.

1.Float

The float data type requires 4 bytes means 32-bits for their storage. The number of digit after decimals point are know as precision are 7. The range of the precision lies between -3.4E38 to +3.4E38.

For Example:

public class Main {
  public static void main(String[] args) {
    float myNum = 2.89f;
    System.out.println(myNum);  
  }
}

Output:

2.89

2.Double

When we need to work with large decimal numbers, we use Double floating data type. It use 8 bytes means 64-bits for their storage. Its digits precision are 15. The range of the precision lies between -1.7e308 to +1.7e308. Note that you should end the value with a “d”.

For example:

public class Main {
  public static void main(String[] args) {
    double myNum = 21.99d;
    System.out.println(myNum);  
  }
}

Output:

21.99
