Summary: Development files for the GNU multiple-precision floating-point library
Development files for the GNU multiple-precision floating-point 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 <>
  - 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 <>
  - 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
    * 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 <>
  - 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
  - Remove tests-tsprintf.patch that's included in the above set.
* Tue Jan 31 2023 Andreas Schwab <>
  - tests-tsprintf.patch: Avoid testsuite failure with glibc >= 2.37
* Mon Jan 09 2023 Richard Biener <>
  - 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
    * 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
    * 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 <>
  - 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 <>
  - package license files correctly
* Fri Nov 18 2022 Richard Biener <>
  - Update to mpfr 4.1.1
    * Bug fixes (see <> 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 <>
  - Add cummulative patch mpfr-4.1.0-p7.diff fixing various bugs.
* Mon Jul 13 2020 Richard Biener <>
  - 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
