MPFR 2.3.2 requires GMP 4.1.0 or higher.

Download

The MPFR 2.3.2 source can be downloaded in the following archive formats:

• mpfr-2.3.2.tar.lzma (tar/lzma, 798 KB, signature),
• mpfr-2.3.2.tar.bz2 (tar/bzip2, 964 KB, signature),

Important note: If the MPFR build fails, please read the section In case of problem of the INSTALL file. In particular, GMP is known for using a different ABI from the default one on some 64-bit platforms, and in such a case, if you do not provide the same compiler flags as those automatically selected by GMP, things will probably go wrong, e.g. libgmp not found error message at configure time (this error message will be improved in future MPFR versions).

Changes from version 2.3.1 to version 2.3.2

• Bug fixes; see the MPFR 2.3.1 page.
• Improved MPFR manual.
• Behavior of mpfr_check_range changed: if the value is an inexact infinity, the overflow flag is set (in case it was lost).
• Function mpfr_init_gmp_rand (only defined when building MPFR without the --with-gmp-build configure option) is no longer defined at all. This function was private and not documented, and was used only in the MPFR test suite. User code that calls it is regarded as broken and may fail as a consequence. Running the old test suite against MPFR 2.3.2 may also fail.
