Function Classes
================

   There are six classes of functions in the GMP library:

  1. Functions for signed integer arithmetic, with names beginning with
     `mpz_'.  The associated type is `mpz_t'.  There are about 150
     functions in this class.

  2. Functions for rational number arithmetic, with names beginning with
     `mpq_'.  The associated type is `mpq_t'.  There are about 40
     functions in this class, but the integer functions can be used for
     arithmetic on the numerator and denominator separately.

  3. Functions for floating-point arithmetic, with names beginning with
     `mpf_'.  The associated type is `mpf_t'.  There are about 60
     functions is this class.

  4. Functions compatible with Berkeley MP, such as `itom', `madd', and
     `mult'.  The associated type is `MINT'.

  5. Fast low-level functions that operate on natural numbers.  These
     are used by the functions in the preceding groups, and you can
     also call them directly from very time-critical user programs.
     These functions' names begin with `mpn_'.  The associated type is
     array of `mp_limb_t'.  There are about 30 (hard-to-use) functions
     in this class.

  6. Miscellaneous functions.  Functions for setting up custom
     allocation and functions for generating random numbers.
