title: working with out of range integers in java
body: <p>Working on a project dealing with RSA encyption and decryption and part of it is working with  this number </p>
  
  <pre><code>int modulus = 270653957405596110781 
  </code></pre>
  
  <p>which is a 68 bit number and i know long only goes up to 64 bit, so how would i address this?</p>
  
  <p>I tried the whole </p>
  
  <pre><code>    public static void main(String [] args){
  
      long modulus = 270653957405596110781L;
  
  
  }
  </code></pre>
  
  <p>thing and still no luck because its a 68 bit number instead of 64 like i said.</p>
