     var string_value = String(number);
     string_value = number.toString();
      var n = 17;
      binary_string = n.toString(2);//Evaluates to "10001"
      octal_string = "0" + n.toString(8);        //Evaluates to "021"
      hex_string = "0x" + n.toString(16);      //Evaluates to "0x11"
      var n = 123456.789;
      n.toFixed(0);   //"1234567"
      n.toFixed(2);  //"123456.79"
      n.toExponential(1);      //"1.2e+5"
      n.toExponential(3);      //"1.235e+5"
      n.toPrecision(4);         //"1.235e+5"
      n.toPrecision(7);         //"123456.8"
