• 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 f1 = 234.5f

Program:

 public class FloatDataType {

   public static void main(String []args) {
      // this is declaration and initialization of variable a
	  // datatype is float
	  float a = 234.5f;
	  // this is declaration and initialization of variable b
	  // datatype is float
      float b = 234.565f;
      System.out.println(a); // it will print a variable
      System.out.println(b); // it will print b variable
      
   }
}

Output:

234.5
234.565
