 Rational Number Functions
 *************************
 
 This chapter describes the GMP functions for performing arithmetic on
 rational numbers.  These functions start with the prefix `mpq_'.
 
    Rational numbers are stored in objects of type `mpq_t'.
 
    All rational arithmetic functions assume operands have a canonical
 form, and canonicalize their result.  The canonical from means that the
 denominator and the numerator have no common factors, and that the
 denominator is positive.  Zero has the unique representation 0/1.
 
    Pure assignment functions do not canonicalize the assigned variable.
 It is the responsibility of the user to canonicalize the assigned
 variable before any arithmetic operations are performed on that
 variable.
 
  - Function: void mpq_canonicalize (mpq_t OP)
      Remove any factors that are common to the numerator and
      denominator of OP, and make the denominator positive.
