title: What data is stored in the symbol table for a number lexeme?
body: <p>Im reading the <strong>Dragon Book</strong>.Im just a beginner trying to understand basic stuff.On Page 113 i can see the following statement(Underlined)</p>
  
  <p><img src="https://i.stack.imgur.com/sD7Js.png" alt="enter image description here"></p>
  
  <p>From what i understand the symbol table stores the variable name and the some details like the type,scope etc.So a character 0 is found by the Lexical analyzer,it matches the pattern for a number so it uses the <em>tokenname</em> number so  token becomes <code>&lt;number,attrb&gt;</code> .
  As per the snippet i have mentioned above, i don't understand what data is stored in the symbol table for numbers,is the value for the number stored in the symbol table?</p>
  
  <p><strong>EDIT:</strong></p>

  <p>In the snipped above the token number is given an integer attribute.And you can see it mentioning <strong><em>stored</em></strong> ,where exactly is this stored if not in symbol table? Does it store the character string somewhere and  use an attribute entry in the symbol table to point to it?If then where is the character string stored?</p>
