 21.2.7 Operations on Integer Values
 -----------------------------------
 
  -- Scheme Procedure: odd? n
  -- C Function: scm_odd_p (n)
      Return `#t' if N is an odd number, `#f' otherwise.
 
  -- Scheme Procedure: even? n
  -- C Function: scm_even_p (n)
      Return `#t' if N is an even number, `#f' otherwise.
 
  -- Scheme Procedure: quotient
      Return the quotient of the numbers X and Y.
 
  -- Scheme Procedure: remainder
      Return the remainder of the numbers X and Y.
           (remainder 13 4) => 1
           (remainder -13 4) => -1
 
  -- Scheme Procedure: modulo
      Return the modulo of the numbers X and Y.
           (modulo 13 4) => 1
           (modulo -13 4) => 3
 
  -- Scheme Procedure: gcd
      Return the greatest common divisor of all arguments.  If called
      without arguments, 0 is returned.
 
  -- Scheme Procedure: lcm
      Return the least common multiple of the arguments.  If called
      without arguments, 1 is returned.
