Java Float longValue() Method

The longValue() method of Java Float class returns the value of this float object as a long after narrowing the primitive values or by casting to type long.

Syntax:

Parameters:

Return Value:

The longValue() method returns the float value corresponding to this Float which has been converted to type long.

Example 1

  public class FloatLongValueExample1{      public static void main(String[] args) {          float f1 = 9655;          Float f2 = new Float(f1);          // return the long value of double object          Long val1 = f2.longValue();          System.out.println(“1. “+”Long value for “+f1+” = “+val1);         //will return the long value by narrowing the primitive value          Float f3 = new Float(999657587698541166666633335679.675);          System.out.println(“2. “+”Long value for “+f3+” = “+f3.longValue());          //passing negative integer          Float f4 = new Float(-86776985679.88675);          System.out.println(“3. ‘+”Long value for “+f4+” = “+f4.longValue());          //passing maximum value          Float f5 = Float.MAX_VALUE;          System.out.println(“4. “+”Long value for “+f5+” = “+f5.longValue());          //passing minimum value          Float f6 = Float.MIN_VALUE;          System.out.println(“5. “+”Long value for “+f6+” = “+f6.longValue());            Float f7 = Float.MIN_NORMAL;          System.out.println(“7. “+”Long value for “+f7+” = “+f7.longValue());          }  }

Output:

1. Long value for 9655.0 = 9655  2. Long value for 9.996576E29 = 9223372036854775807  3. Long value for -8.6776988E10 = -86776987648  4. Long value for 3.4028235E38 = 9223372036854775807  5. Long value for 1.4E-45 = 0  7. Long value for 1.17549435E-38 = 0

Example 2

  import java.util.Scanner;    public class FloatLongValueExample2 {      public static void main(String[] args) {          Scanner scanner = new Scanner(System.in);          System.out.println(“Enter three numbers”);          System.out.print(“1.”);     Float f1 =scanner.nextFloat();          System.out.print(“2.”);     Float f2 =scanner.nextFloat();          System.out.print(“3.”);     Float f3 =scanner.nextFloat();          //adding the long values          Long val1= f1.longValue()+f2.longValue()+f3.longValue();          System.out.println(“1.Sum:     “+f1.longValue()+”+”+f2.longValue()+”+”+f3.longValue()+” = “+ val1);          //multiplying long value          Long val2= f1.longValue()*f2.longValue()*f3.longValue();          System.out.println(“1.Mul:     “+f1.longValue()+”*”+f2.longValue()+”*”+f3.longValue()+” = “+ val2);        }  }

Output:

Enter three numbers  1.67.99  2.100.76  3.78.77  1.Sum:     67+100+78 = 245  1.Mul:     67*100*78 = 522600

Example 3

  import java.util.Scanner;    public class FloatLongValueExample3 {      public static void main(String[] args) {          Scanner scanner = new Scanner(System.in);          System.out.println(“Enter your annual income”);          Float d1 = scanner.nextFloat();          Long val1 = d1.longValue() / 12;          System.out.println(“Your monthly income is:”+val1);           if (val1 < 30000 ) {              Long l1= val1 + 2000;              System.out.println(“You got an increment of 5000.nYour new salary is:” +l1);          }          else if (val1 >30000 && val1< 80000) {              Long l1= val1 + 5000;              System.out.println(“You got an increment of 5000.nYour new salary is:” +l1);          } else if (val1 > 80000 && val1<100000) {              Long l2= val1 + 8000;              System.out.println(“You got an increment of 8000.nYour new salary is:” + l2);          } else if(val1>100000) {              Long l3= val1 + 15000;              System.out.println(“You got an increment of 15000.nYour new salary is:” + l3);          }      }  }
