title: Memory and irrationality and floating numbers
body: <p>Some numbers can not be stored in "memory bits" as their binary representation would make them go endlessly.</p>
  
  <p>In binary 11.111011101110... this is not the exact number. I can't remember exactly what it is right now. </p>
  
  <p>But we can think of it "like an irrational number" in our base 10 that goes on infinitely after decimal place. </p>
  
  <p>Some rational numbers face this problem when converted to base 2. 
  So how do we...</p>
  
  <p>1) represent them?</p>
  
  <p>2) calculate them with computer programs?</p>
  
  <p>3) perform operations on them?</p>
  
  <p>Edit: 
  To remove Confusion and say thanks:</p>
  
  <p>Ok I said in above post --> to view it or think it like a irrational or a number going long and long in decimal place. please read the word "like". </p>
  
  <p>Now i have a number 0.2 this simple number cannot be represented in binary form. so how to perform Operations over it.</p>
  
  <p>Other Questions are still unsolved .</p>
  
  <p>well just to mention for my belief in people here:</p>
  
  <p>Well go for "library" or approximately storage is not an answer for geeks of stackoverflow as their are certain applications where it is important to have the numbers as they are. </p>
