Float byteValue() method in Java with Examples
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:
import java.lang.*;
public class GFG {
public static void main(String[] args)
{
Float value = 1023f;
byte byteValue = value.byteValue();
System.out.println( "Byte Value of num = " + byteValue);
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.
import java.lang.*;
public class GFG {
public static void main(String[] args)
{
Float value = -1023f;
byte byteValue = value.byteValue();
System.out.println( "Byte Value of num = " + byteValue);
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.
import java.lang.*;
public class GFG {
public static void main(String[] args)
{
Float value = 11 .24f;
byte byteValue = value.byteValue();
System.out.println( "Byte Value of num = " + byteValue);
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
