Is there a way to display a floating number in its' binary form?

Question

Let's say I have a floating number in java. How can I print it in it's binary form? Is there a simple method to use in the java library? I am talking about IEEE 754 floating point. Or would I have to write it from scratch?

I'd also like to print it out.

I think [this](http://stackoverflow.com/a/397700/645270) will work (scroll down for more tips) — keyser, Apr 23 '14 at 18:09
I answered something very similar to this yesterday - see [Java float to IEEE-754 hexadecimal?](http://stackoverflow.com/questions/23230748/java-float-to-ieee-754-hexadecimal) — Dawood ibn Kareem, Apr 23 '14 at 18:10
You can do `Integer.toBinaryString(Float.floatToIntBits(f))` — Alexis C., Apr 23 '14 at 18:11
@munchschair I have tried so many ways to convert double into binary but no success and now you need it only for float. :) — Braj, Apr 23 '14 at 18:31

Integer.toBinaryString(Float.floatToIntBits(FloatNumber));

Example:

class FloatToBinary { 
      public static void main( String ... args ) { 

      int BitRep =   Float.floatToIntBits(12345.12346f); //Bit Representation of the Float
      System.out.println(BitRep); //1178657918

      String BinString = Integer.toBinaryString(BitRep); //Binary representation in String
      System.out.println(BinString); //1000110010000001110010001111110



             }
        }

EDIT

Looks like an identical question has already been answered: how to convert a string of binary values to a float and vice-versa

What if you want it signed? – munchschair Apr 23 '14 at 22:01 — munchschair, Apr 23 '14 at 22:01
