The floatToRawIntBits() method in Float Class is a built-in function in java that returns a representation of the specified floating-point value according to the IEEE 754 floating-point “single format” bit layout, preserving Not-a-Number (NaN) values.
Syntax:
public static int floatToRawIntBits(float val)
Parameter: The method accepts only one parameter val which specifies a floating-point number.
Return Values: The function returns the bits that represent the floating-point number. However there are 3 special cases:
- If the argument is positive infinity, the result is 0x7f800000.
- If the argument is negative infinity, the result is 0xff800000.
- If the argument is NaN, the result is 0x7fc00000.
Below programs illustrates the use of Float.floatToRawIntBits() method:
Program 1:
// Java program to demonstrate// Float.floatToRawIntBits() methodimport java.lang.*; class Gfg1 { public static void main(String args[]) { float val = 1.5f; // function call int answer = Float.floatToRawIntBits(val); // print System.out.println(val + " in raw int bits: " + answer); }} |
Output:
1.5 in raw int bits: 1069547520
Program 2:
// Java program to demonstrate// Float.floatToRawIntBits() method import java.lang.*; class Gfg1 { public static void main(String args[]) { float val = Float.POSITIVE_INFINITY; float val1 = Float.NEGATIVE_INFINITY; float val2 = Float.NaN; // function call int answer = Float.floatToRawIntBits(val); // print System.out.println(val + " in raw int bits: " + answer); // function call answer = Float.floatToRawIntBits(val1); // print System.out.println(val1 + " in raw int bits: " + answer); // function call answer = Float.floatToRawIntBits(val); // print System.out.println(val2 + " in raw int bits: " + answer); }} |
Output:
Infinity in raw int bits: 2139095040 -Infinity in raw int bits: -8388608 NaN in raw int bits: 2139095040
