| Arithmetic operations |  | 
 | Performs various arithmetic operations on fix. 
  | fix | + | aNumeric | Addition |  
  | fix | -- | aNumeric | Subtraction |  
  | fix | * | aNumeric | Multiplication |  
  | fix | / | aNumeric | Division |  
  | fix | % | aNumeric | Modulo |  
  | fix | ** | aNumeric | Exponentiation |  | | Bit operations |  | 
 | Performs various operations on the binary representations of the Fixnum.
| ~ fix | Invert bits |  
  | fix | | | aNumeric | Bitwise OR |  
  | fix | & | aNumeric | Bitwise AND |  
  | fix | ^ | aNumeric | Bitwise EXCLUSIVE OR |  
  | fix | << | aNumeric | Left-shift aNumeric bits |  
  | fix | >> | aNumeric | Right-shift aNumeric
      bits (with sign extension) |  | | <=> | fix <=> aNumeric
        -> -1, 0, +1 | 
 | Comparison---Returns -1, 0, or +1 depending on whether fix is less
      than, equal to, or greater than aNumeric. This is the
      basis for the tests in Comparable. | | [ ] | fix[ n ] -> 0, 1 | 
 | Bit Reference---Returns the nth bit in the binary
      representation of fix, where fix[0] is the least significant
      bit. produces:|

 | | id2name | fix.id2name -> aString or nil | 
 | Returns the name of the object whose symbol
      id is the value of fix.  If there is no symbol in the symbol
      table with this value, returns nil.id2namehas nothing to do with theObject.idmethod. See alsoString#internon page 376 and classSymbolon page 388.

  | id     = symbol.to_i | » | 8978 |  
  | id.id2name | » | "@inst_var" |  | | size | fix.size -> aFixnum | 
 | Returns the number of bytes in the machine representation
      of a Fixnum. | | to_f | fix.to_f -> aFloat | 
 | Converts fix to a Float. | | to_i | fix.to_i -> fix | 
 | Returns fix. | | to_s | fix.to_s -> aString | 
 | Returns a string containing the decimal representation of self. |
