 /* Todo list
  * ---------
  * Add all MPFR and MPC functions as context methods.
  * All MPFR and MPC functions need to set exponent range on entry. The
  *    current approach where only set_context() and context.__enter__ set
  *    the exponent range fails for context methods.
  * Should a read-only (or template) context prevent the setting of
  *    exception flags?
  * Add context option to control the result of integer division:
  *    integer (mpz), exact (mpq), or true (mpfr).
  * Add modular arithmetic functions.
  * Implement Chinese Remainder Theorem.
  * Update PRP code.

/*
 * originally written for GMP-2.0 (by AMK...?)
 * Rewritten by Niels Möller, May 1996
 *
 * Version for GMP-4, Python 2.X, with support for MSVC++6,
 * addition of mpf's, &c: Alex Martelli (now aleaxit@gmail.com, Nov 2000).
 * cleanups & reorgs leading to 1.0: Alex Martelli (until Aug 2003)
 * further cleanups and bugfixes leading to 1.01, Alex Martelli (Nov 2005)
 * minor bugfixes+new decimal (&c) support to 1.02, Alex Martelli (Feb 2006)
 * various bugfixes for 64-bit platforms, 1.03, aleaxit and casevh (Jun 2008)
 * rich comparisons, 1.04, aleaxit and casevh (Jan 2009)
 * support for Python 3.x, 1.10, casevh (Oct 2009)
 *
 * Some hacks by Gustavo Niemeyer <niemeyer@conectiva.com>.
 *
 *   0.1, pre-alpha; date: 2000-11-06  first placed on sourceforge
 *
 *   0.2, still pre-alpha: 2000-11-15: bugfixes re formatting (tx, Peanu!)
 *   no tags on oct() and hex() of mpz's
 *   insert 'tagoff' in options (gmpy.mpz() vs mpz() in repr) (for Peanu!)
 *   speedups for _nonzero & _cmp (tx, Peanu!)
 *   slight speedup (7/8%?) for excess reallocs 4<->8 bytes (Peanu's help!)
 *   added copy/fcopy; bin; fib; remove
 *
 *   0.3, still pre-alpha, but...:
 *   performance tweaks via mpz-caching & fixed-constants
 *   added get/set functions for zcache, zco min/max
 *   added get-only function for versions (of gmp, and of gmpy)
 *   removed all 'traces' of mutability (to be re-done... much later!)
 *   cleaned up all of the mpz_cmp_ui(X,0) to mpz_sgn(X)
 *   cleaned up Py_BuildValue usage (N vs O, explicit-() for tuples)
 *   added numdigits, lowbits, root, next_prime, invert, popcount,
 *      hamdist, scan0, scan1
 *   renamed bin to bincoef
 *
 *   0.4:
 *   split gmpy.c/gmpy.h introducing C-API interface (Pearu's suggestion)
 *   cleanup some casts using Pearu's new macros
 *   further cache-tweaks at Pearu's suggestion (macros introduced)
 *   added sign (Pearu's request), getbit, setbit
 *   added docstrings
 *   renamed copy functions to start with _ ('internal, private')
 *   added .comb as a synonym of .bincoef
 *
 *   0.5:
 *   added jacobi, legendre, kronecker
 *   added random-number generation, seed set/save, shuffling
 *   added mpq (at last!-)
 *
 *   0.6: (lots of good ideas from Pearu once more!-):
 *   fixed silly bugs in kronecker and mpq_abs
 *   gmpy-level workaround for scan0/scan1 bugs (?) in GMP 3.1.1
 *   added qdiv; anynum->mpq substituted for all such conversions
 *       (also anynum->mpz and anynum->mpf by analogy, with care!)
 *   added global.fcoform for optional use of intermediate string in
 *       float2mpf (used for any float->mpf conversion)
 *   added set_fcoform function for global.fcoform access
 *   general cleanup of sources; added alloca for MSVC++;
 *       many sundry minor bugfixes & uniformization;
 *       a little useful refactoring (more would be good...)
 *   added caching of mpq objects
 *   power for mpq
 *   Stern-Brocot algorithm for mpf->mpq (also exposed as f2q)
 *       also used for float->mpq
 *       with stricter tracking of mpf's requested-precision
 *       added getrprec method to mpf, getrprec module-function
 *   exposed ceil, floor and trunc methods/functions for mpf's
 *   changed a couple exceptions from Value to ZeroDivision
 *   added 'qual' and 'floa' options to gmpy.rand
 *
 *   0.7: (good feedback from Keith Briggs, some advice from Tim Peters
 *      and Fred Lundh -- thanks all!):
 *   fixed bug of '"%d" where "%ld" was meant' in many places
 *      and other sundry minor warnings given by gcc
 *   fixed hash (delegating to Python) so mp[nqz](x) will
 *      produce the same value as hash(x) for any Python number x
 *   workaround for GMP 3.1.1 bug, mpz_root wrongly returning
 *      'exact' for non-exact root if dest==source, which stopped
 *      needed value-error for inexact mpq**mpq operations
 *   determined correct 'actual precision' of floats
 *   explicitly stored precision with binary-form mpf's
 *   extended explicit-bits request to all ->mpf operations
 *     (good in itself, plus, preparing for future MPFR)
 *   removed the limitation of no binary-form for <0 mpz
 *   introduced macros to parse args, for conciseness
 *
 *   0.8: (again, requests & suggestions by great Pearu!)
 *   raise test coverage 72.5% -> 90.0%
 *   introduced callbacks (not documented/tested for now;
 *       Pearu will test/support/document in PySymbolic)

 *   workaround for GMP bug(?s?) in mpz_fits_... (?)
 *   added exposure of mpf_ sqrt and pow_ui
 *
 *   0.9: (ditto)
 *   change ValueError to OverflowError for 'too-large' errors
 *   fix bug in mpq_pow (negative base, exp. with odd denominator)
 *       (fix now corrected -- _even_ denominator is the error!)
 *   fixed gcc warnings reported by K. Briggs
 *
 *   0.9b:
 *   support GMP 4 (but added no GMP4-only functionality yet)
 *
 *   0.9c:
 *   updated tests to 0.9, better coverage
 *
 *   1.0:
 *   minor cleanups, ensure support for Python 2.3
 *   fixed misdiagnosis of some argument counts in macro
 *     SELF_ONE_ARG_CONVERTED (tx to Paul Rubin!)

 *     as well as Python 2.2 and 2.3 (on MacOSX and Linux)
 *   fixed memory leak on divm (thanks to mensanator@aol.com)
 *   fixed bug on mpq('123') [[str2mpq on string w/o a slash]]
 *   added floordiv and truediv operators, and tests for them
 *   NOT tested on GMP 3 (have none left around...), ONLY on GMP 4.*
 *
 *   1.02:
 *   fix warning in comparison of mpq's
 *   added support of mpq('12.34') [[string w/o a slash, but with a dot]]
 *   fixes for 64-bit build (thanks to a patch by dmcooke)
 *   added experimental support for decimal.Decimal (and user-coded types)
 *      via wider use of special conversion methods (if present) and their
 *      sly insertion on-the-fly into the decimal.Decimal class (!)
 *   two bugfixes, thanks to Simon Burton
 *   Brought back into C89 compliance (thanks to Chip Turner), had
 *      drifted to C99 (declarations in the middle of the code).
 *   Python 2.5 support (Py_ssize_t, __index__) thanks to Chip Turner
 *   Pushed coverage to 93.3% (missing only "sanity check" level error
 *      tests [mostly for out-of-memory conditions], output to stderr
 *      conditioned by global.debug, & a couple of very obscure cases)
 *
 *   1.03:
 *   Fixed the bug that caused crashes on gmpy.mpf(float('inf')) and
 *      other such conversions, implicit and explicit
 *   Fixed a bug in get_zconst's prototype affecting 64-bit machines,

 ************************************************************************
 *
 * Discussion on sizes of C integer types.
 *
 * GMP, MPIR, MPFR, and MPC use typedef to create integer objects with
 * different sizes. It can become confusing to map the different types
 * onto the standard C types used by Python's C API. Below are external
 * types and how they map to C types. The assumptions are verified when
 * the module is initialized.
 *
 * mp_limb_t: This is usually an 'unsigned long' but is an 'unsigned
 *     long long' on MPIR/64-bit Windows.
 *
 * mp_bitcnt_t: This is usually an 'unsigned long' but is an 'unsigned
 *     long long' on MPIR/64-bit Windows. 'size_t' is the best match.
 *
 * mp_size_t: This is a 'long'.
 *
 * mpfr_rnd_t: This is an 'int'.
 *
 * mpfr_prec_t: This is a 'long'.
 *
 * mpfr_sign_t: This is an 'int'.
 *
 * mpfr_exp_t: This is currently the same as mp_exp_t but will change
 *     to a signed 64-bit integer in the future.
 *
 * mpc_rnd_t: This is an 'int'.
 *
 * mpc_prec_t: See mpfr_exp_t.
