The MPFR library is a C library for multiple-precision floating-point computations with exact rounding (also called correct rounding). It is based on the GMP multiple-precision library.
LGPL-3.0-or-later
* Tue Aug 22 2023 rguenther@suse.com
- Update to mpfr 4.2.1
* Includes all fixes from mpfr-4.2.0-cummulative.patch which is
subsequently removed.
* Improved MPFR manual.
* Configure tests: replaced the test of the link with GMP, in order
to avoid the use of a function without a prototype (Autoconf issue), as
this is obsolescent in ISO C. The new test should be more robust.
* Wed Jun 07 2023 rguenther@suse.com
- Update mpfr-4.2.0-cummulative.patch, adds patches fixing the following bugs
* the mpfr_reldiff function, which computes |b-c|/b, is buggy on special
values, e.g. on the following (b,c) values: (+Inf,+Inf) gives ±0
instead of NaN (like NaN/Inf); (+0,+0) gives 1 instead of NaN (like 0/0);
(+0,1) gives 1 instead of Inf (like 1/0). Moreover, the sign of 0 for
(+Inf,+Inf) or (-Inf,-Inf) is not set, i.e. it is just the sign of the
destination before the call; as a consequence, results are not even
consistent.
* the reuse tests are incomplete: the sign of a result zero is not checked,
so that it can miss bugs (one of the mpfr_reldiff bugs mentioned above,
in particular).
* the general code for the power function (mpfr_pow_general internal
function) has two bugs in particular cases: the first one is an incorrect
computation of the error bound when there has been an intermediate
underflow or overflow (in such a case, the computation is performed
again with a rescaling, thus with an additional error term, but there is
a bug in the computation of this term), so that the result may be
rounded incorrectly (in particular, a spurious overflow is possible);
the second one occurs in a corner case (destination precision 1,
rounding to nearest, and where the rounded result assuming an unbounded
exponent range would be 2emin-2 and the exact result is larger than this
value), with the only consequence being a missing underflow exception
(the underflow flag is not set).
* the mpfr_compound_si function can take a huge amount of memory and time
in some cases (when the argument x is a large even integer and xn is
represented exactly in the target precision) and does not correctly
detect overflows and underflows
* MPFR can crash when a formatted output function is called with
%.2147483648Rg in the format string.
* Tue Apr 18 2023 rguenther@suse.com
- Add mpfr-4.2.0-cummulative.patch, cummulative patches for
mpfr 4.2.0:
* A test of the thousands separator in tsprintf.c is based on the
output from the GNU C Library up to 2.36, which is incorrect.
* The mpfr_ui_pow_ui function has infinite loop in case of overflow.
* The tfprintf and tprintf tests may fail in locales where decimal_point
has several bytes, such as ps_AF.
* In particular cases that are very hard to round, mpfr_rec_sqrt may yield
a stack overflow due to many small allocations in the stack, based on
alloca().
- Remove tests-tsprintf.patch that's included in the above set.
* Tue Jan 31 2023 schwab@suse.de
- tests-tsprintf.patch: Avoid testsuite failure with glibc >= 2.37
* Mon Jan 09 2023 rguenther@suse.com
- Update to mpfr 4.2.0
* New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu,
mpfr_atanu and mpfr_atan2u.
* New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi,
mpfr_atanpi and mpfr_atan2pi.
* New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and
mpfr_compound_si.
* New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj
and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for
mpfr_pow_sj).
* Bug fixes.
In particular, for the formatted output functions (mpfr_printf, etc.),
the case where the precision consists only of a period has been fixed
to be like ".0" as specified in the ISO C standard, and the manual has
been corrected and clarified.
The macros of the custom interface have also been fixed: they now behave
like functions (except a minor limitation for mpfr_custom_init_set).
- Remove mpfr-4.1.1-patch01.patch which is included in the new release.
* Thu Nov 24 2022 rguenther@suse.com
- Add mpfr-4.1.1-patch01.patch to fix bug with code using
the mpfr_custom_get_kind macro.
* Sat Nov 19 2022 andreas.stieger@gmx.de
- package license files correctly
* Fri Nov 18 2022 rguenther@suse.com
- Update to mpfr 4.1.1
* Bug fixes (see <https://www.mpfr.org/mpfr-4.1.0/#fixed> and/or the
ChangeLog file), in particular for macros implementing functions.
* Improved manual formatting.
* Accumulated bugfixes
- Remove mpfr-4.1.0-p7.diff, all patches are contained in the
new version.
- Update mpfr.keyring
* Fri Feb 12 2021 rguenther@suse.com
- Add cummulative patch mpfr-4.1.0-p7.diff fixing various bugs.
* Mon Jul 13 2020 rguenther@suse.com
- Update to mpfr 4.1.0
* New function mpfr_get_str_ndigits about conversion to a string of digits.
* New function mpfr_dot for the dot product (incomplete, experimental).
* New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available only
when MPFR has been built with decimal float support).
* New function mpfr_cmpabs_ui.
* New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
* The mpfr_out_str function now accepts bases from -2 to -36, in order to
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
assertion failure, as with other invalid bases).
* Shared caches: cleanup; really detect lock failures (abort in this case).
* The behavior of the formatted output functions (mpfr_printf, etc.) with
an empty precision field has improved: trailing zeros are kept in a way
similar to the formatted output functions from C.
* Improved mpfr_add and mpfr_sub when all operands have a precision equal to
twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
* Optimized the tuning parameters for various architectures.
* Improved test coverage to 98.6% of code for x86_64.
* Bug fixes.
* MPFR manual: corrected/completed the mpfr_get_str description in order to
follow the historical behavior and GMP's mpf_get_str function.

* Cummulative bugfix release, includes mpfr-4.0.1-cummulative-patch.patch.
* Thu May 17 2018 antoine.belvire@opensuse.org
- Fix %install_info_delete usage:
* It has to be performed in %preun not in %postun.
* See https://en.opensuse.org/openSUSE:Packaging_Conventions_RPM_Macros#.25install_info_delete.
* Wed May 02 2018 rguenther@suse.com
- Add mpfr-4.0.1-cummulative-patch.patch. Fixes
* A subtraction of two numbers of the same sign or addition of two
numbers of different signs can be rounded incorrectly (and the
ternary value can be incorrect) when one of the two inputs is
reused as the output (destination) and all these MPFR numbers
have exactly GMP_NUMB_BITS bits of precision (typically, 32 bits
on 32-bit machines, 64 bits on 64-bit machines).
* The mpfr_fma and mpfr_fms functions can behave incorrectly in case
of internal overflow or underflow.
* The result of the mpfr_sqr function can be rounded incorrectly
in a rare case near underflow when the destination has exactly
GMP_NUMB_BITS bits of precision (typically, 32 bits on 32-bit
machines, 64 bits on 64-bit machines) and the input has at most
GMP_NUMB_BITS bits of precision.
* The behavior and documentation of the mpfr_get_str function are
inconsistent concerning the minimum precision (this is related to
the change of the minimum precision from 2 to 1 in MPFR 4.0.0). The
get_str patch fixes this issue in the following way: the value 1
can now be provided for n (4th argument of mpfr_get_str); if n = 0,
then the number of significant digits in the output string can now
be 1, as already implied by the documentation (but the code was
increasing it to 2).
* The mpfr_cmp_q function can behave incorrectly when the rational
(mpq_t) number has a null denominator.
* The mpfr_inp_str and mpfr_out_str functions might behave
incorrectly when the stream is a null pointer: the stream is
replaced by stdin and stdout, respectively. This behavior is
useless, not documented (thus incorrect in case a null pointer
would have a special meaning), and not consistent with other
input/output functions.
* Wed Feb 07 2018 astieger@suse.com
- update to 4.0.1:
* Improved MPFR manual
* bug fixes, including mpfr_div_ui, mpfr_div rounding issue
* Tue Jan 02 2018 rguenther@suse.com
- Update to mpfr 4.0.0
* The "dinde aux marrons" release.
* MPFR now depends on GMP 5.0+ instead of 4.1+.
* API change:
Applications that call GMP's mp_set_memory_functions function to change
the allocators must first call the new function mpfr_mp_memory_cleanup
in all threads where MPFR is potentially used; this new function is
currently equivalent to mpfr_free_cache.
The reason is that the way memory allocation is done by MPFR has changed
(again), so that the current GMP allocators are used (since for some
applications, the old allocators may become invalid).
Note: Freeing the caches like this might have a performance impact on some
particular applications; if this is an issue, this could be handled for a
future MPFR version.
* Mini-gmp support via the --enable-mini-gmp configure option (experimental).
* The minimum precision MPFR_PREC_MIN is now 1, with rounding defined as
in the errata of IEEE 754-2008 and in the following IEEE 754 revision
(ties rounded away from zero).
* Shared caches for multithreaded applications.
New function mpfr_free_cache2.
* Partial support of MPFR_RNDF (faithful rounding).
* New functions: mpfr_fpif_export and mpfr_fpif_import to export and import
numbers in a floating-point interchange format, independent both on the
number of bits per word and on the endianness.
* New function mpfr_fmodquo to return the low bits of the quotient
corresponding to mpfr_fmod.
* New functions mpfr_flags_clear, mpfr_flags_set, mpfr_flags_test,
mpfr_flags_save and mpfr_flags_restore to operate on groups of flags.
* New functions mpfr_set_float128 and mpfr_get_float128 to convert from/to
the __float128 type (requires --enable-float128 and compiler support).
* New functions mpfr_buildopt_float128_p and mpfr_buildopt_sharedcache_p.
* New functions mpfr_rint_roundeven and mpfr_roundeven, completing the
other similar round-to-integer functions for rounding to nearest with
the even-rounding rule.
* New macro mpfr_round_nearest_away to add partial emulation of the
rounding to nearest-away (as defined in IEEE 754-2008).
* New functions mpfr_nrandom and mpfr_erandom to generate random numbers
following normal and exponential distributions respectively.
* New functions mpfr_fmma and mpfr_fmms to compute a*b+c*d and a*b-c*d.
* New function mpfr_rootn_ui, similar to mpfr_root, but agreeing with the
rootn function of the IEEE 754-2008 standard.
* New functions mpfr_log_ui to compute the logarithm of an integer,
mpfr_gamma_inc for the incomplete Gamma function.
* New function mpfr_beta for the Beta function (incomplete, experimental).
* New function mpfr_get_q to convert a floating-point number into rational.
* The mpfr_dump function is now described in the manual; its output format
has slightly changed.
* The mpfr_eint function now returns the value of the E1/eint1 function
for negative argument.
* The behavior of the mpfr_set_exp function changed, as it could easily
yield undefined behavior in some cases (this modifies both the API and
the ABI).
* In function mpfr_urandom, the next random state no longer depends on the
current exponent range and the rounding mode. The exceptions due to the
rounding of the random number are now correctly generated, following the
uniform distribution.
* Functions mpfr_grandom and mpfr_root are deprecated and will be removed
in a future release.
* Complete rewrite of function mpfr_sum, which now works in all cases (the
old one could take all the memory and/or crash with inputs of different
magnitudes in case of huge cancellation or table maker's dilemma). The
sign of an exact zero result is now specified, and the return value is
now the usual ternary value. Note that the position of "const" in the
mpfr_sum prototype has been fixed (the manual was correct); user code
should not be affected.
* Old, deprecated macros mpfr_add_one_ulp and mpfr_sub_one_ulp removed.
The mpfr_next* functions should be used instead.
* Internally, improved caching: a minimum of 10% increase of the precision
is guaranteed to avoid too many recomputations.
* Added internal small-precision mpz_t pool, which aims to avoid the
overhead of memory allocation, in particular.
New function mpfr_free_pool.
* Added configure option --enable-assert=none to avoid checking any assertion.
* The --enable-decimal-float configure option no longer requires
- -with-gmp-build, and support for decimal floats is now automatically
detected by default (similarly for support for __float128).
* Updated tuning parameters.
* Better support for Automake 1.13+ (now used to generate the tarball).
* Dropped K&R C compatibility.
* Improved MPFR manual.
* New MPFRbench program (see the tools/bench directory).
* Major speedup in mpfr_add, mpfr_sub, mpfr_mul, mpfr_div and mpfr_sqrt when
all operands have the same precision and this precision is less than twice
the number of bits per word, e.g., less than 128 on a 64-bit computer.
* Speedup by a factor of almost 2 in the double <--> mpfr conversions
(mpfr_set_d and mpfr_get_d).
* Speedup in mpfr_log1p and mpfr_atanh for small arguments.
* Speedup in the mpfr_const_euler function (contributed by Fredrik Johansson),
in the computation of Bernoulli numbers (used in mpfr_gamma, mpfr_li2,
mpfr_digamma, mpfr_lngamma and mpfr_lgamma), in mpfr_div, in mpfr_fma
and mpfr_fms.
* Test coverage: 96.3% lines of code.
* Bug fixes. In particular: a speed improvement when the --enable-assert
or --enable-assert=full configure option is used with GCC; mpfr_get_str
now sets the NaN flag on NaN input and the inexact flag when the conversion
is inexact. For a full list, see http://www.mpfr.org/mpfr-3.1.6/#fixed
and the same section for any previous 3.1.x version (follow the links
in the "Changes..." sections).
* Microsoft Windows: Added support for thread-safe DLL (shared library).
Tested with MinGW, ICC and MSVC.
* Limited pkg-config support.
* Autotools: Under Linux, make sure that the old dtags (when supported)
are used if LD_LIBRARY_PATH is defined; otherwise "make check" would
check an installed, compatible MPFR library found in LD_LIBRARY_PATH
instead of the one that has been built with "make".
* New: optional "make check-gmp-symbols", mainly for binary distributions,
to check that MPFR does not use GMP internal symbols (experimental).
