Java Float floatToIntBits() method

The floatToIntBits() method of Float class returns the specified floating-point value according to the IEEE 754 floating-point ‘single format’ bit layout.

Syntax:

Parameters:

A float type parameter (value) is passed where value is a floating-point number.

Return Value:

The floatToIntBits(float value) method of Float class returns the bits of the given floating-point number.

If the argument is positive infinity, it will return 0x7f800000.
If the argument is negative infinity, it will return 0xff800000.
If the argument is NaN, it will return 0x7fc00000.

Example 1

  public class Float_floatToIntBitsMethod_Example1 {      float f;        // constructor of our class      Float_floatToIntBitsMethod_Example1(float f){            this.f=f;          //converting float to int bytes            System.out.println(”  Equivalent integer bits = “+Float.floatToIntBits(f));      }          public static void main(String[] args) {            Float_floatToIntBitsMethod_Example1 obj= new Float_floatToIntBitsMethod_Example1(67.7f);            }    }  

Test it Now

Output:

Equivalent integer bits = 1116169830

Example 2

  public class Float_floatToIntBitsMethod_Example2 {      public static void main(String[] args) {              //float is conerted to int bits          Float f1=67.5f;          System.out.println(f1+” value in int Bits = “+Float.floatToIntBits(f1));           //argument is positive infinity          Float f2 = new Float(f1/0.0);          System.out.println(f2+” value in int Bits = “+Float.floatToIntBits(f2));            //argument is negative infinity          Float f3 = new Float(0.0/0.0);          System.out.println(f3+” value in int Bits = “+Float.floatToIntBits(f3));              //argument is NaN          Float f4 = new Float(-f1/0.0);          System.out.println(f4+” value in int Bits = “+Float.floatToIntBits(f4));            }    }  

Test it Now

Output:

67.5 value in int Bits = 1116143616  Infinity value in int Bits = 2139095040  NaN value in int Bits = 2143289344  -Infinity value in int Bits = -8388608

Example 3

  public class Float_floatToIntBitsMethod_Example2 {      public static void main(String[] args) {             Float_floatToIntBitsMethod_Example2 obj1= new Float_floatToIntBitsMethod_Example2();           float f1=67.5f;          Float f2 = new Float(f1);                    // called with class object          Float f3= obj1.floatToIntBits(f2);          System.out.println(f1+” value in int Bits = “+f3);                 }    }  

Test it Now

Output:

Error:(12, 23) java: cannot find symbol    symbol:   method floatToIntBits(java.lang.Float)    location: variable obj1 of type com.interf.Float_floatToIntBitsMethod_Example2

The floatToIntBits() is a static method of Float class so, it will always be called with Float class name otherwise, it will give an error like above.
