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() methodimport 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() methodimport 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
