Summary: The GNU multiple-precision floating-point shared library |

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.

* Tue Aug 22 2023 Richard Biener <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 Richard Biener <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 Richard Biener <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 Andreas Schwab <schwab@suse.de> - tests-tsprintf.patch: Avoid testsuite failure with glibc >= 2.37 * Mon Jan 09 2023 Richard Biener <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 Richard Biener <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 <andreas.stieger@gmx.de> - package license files correctly * Fri Nov 18 2022 Richard Biener <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 Richard Biener <rguenther@suse.com> - Add cummulative patch mpfr-4.1.0-p7.diff fixing various bugs. * Mon Jul 13 2020 Richard Biener <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. - Remove mpfr-4.0.2-p6.patch and floating-point-format-no-lto.patch
