Float byteValue() method in Java with Examples
  • Last Updated : 22 Oct, 2018

The java.lang.Float.byteValue() is a built-in method in Java that returns the value of this Float as a byte(by casting to a byte). Basically it used for narrowing primitive conversion of Float type to a byte value.

Syntax:

public byte byteValue()

Parameters: The function does not accept any parameter.

Return Value: This method returns the Float value represented by this object converted to type byte.

Examples:



Input : 12
Output : 12

Input : 1023
Output : -1

Below programs illustrates the java.lang.Float.byteValue() function:

Program 1:




// Program to illustrate the Float.byteValue() method
import java.lang.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        Float value = 1023f;
  
        // Returns the value of Float as a byte
        byte byteValue = value.byteValue();
        System.out.println("Byte Value of num = " + byteValue);
  
        // Another example
        value = 12f;
        byteValue = value.byteValue();
        System.out.println("Byte Value of num = " + byteValue);
    }
}
Output:
Byte Value of num = -1
Byte Value of num = 12

Program 2 : Demonstrates the byte value for a negative number.




// Java code to illustrate java.lang.Float.byteValue() method
import java.lang.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        Float value = -1023f;
  
        // Returns the value of Float as a byte
        byte byteValue = value.byteValue();
        System.out.println("Byte Value of num = " + byteValue);
  
        // Another example
        value = -12f;
        byteValue = value.byteValue();
        System.out.println("Byte Value of num = " + byteValue);
    }
}
Output:
Byte Value of num = 1
Byte Value of num = -12

Program 3 : When a decimal value is passed in argument.




// Program to illustrate java.lang.Float.byteValue() method
  
import java.lang.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        Float value = 11.24f;
  
        // Returns the value of Float as a byte
        byte byteValue = value.byteValue();
        System.out.println("Byte Value of num = " + byteValue);
  
        // Another example
        value = 6.0f;
        byteValue = value.byteValue();
        System.out.println("Byte Value of num = " + byteValue);
    }
}
Output:
Byte Value of num = 11
Byte Value of num = 6
