Unlike the 'mpf' function class, 'mpfr' is a smooth -extension to the IEEE P754 arithmetic. In fact, setting the precision to 53, -'mpfr' functions should work exactly like IEEE doubles. +You should have received a copy of the GNU Lesser General Public License +along with the MPFR Library; see the file COPYING.LIB.

It is -also not as well tested as the other parts of GMP. The original 'mpfr' library -integrated into GMP was version 0.4. -This code might at some point replace the 'mpf' library. +The MPFR distribution contains the following files: - - - MORE INFORMATION - -This code was contributed by the French FIABLE project. Please see the 'mpfr' -project page for more info, http://www.loria.fr/projets/mpfr/ - - - - INSTALLATION - -To install this package to the libgmp library you add the "--enable-mpfr" to -configure. This has the unfortune side effect that all programs using GMP -will also depend on 'libm'. - -Two test cases were disabled, 'tcmp' 'tset_d'. - - - - REPORTING BUGS - -Report bugs to bug-gmp@gnu.org and mpfr@loria.fr. What information is -needed in a good bug report is described in the manual. The same address -can be used for suggesting modifications and enhancements. - - - - NOTES FROM THE ORIGINAL INSTALL DOCUMENT - -We tested the installation with GMP 2.0.2 on the following architectures: - - Pentium II and III/Linux 2.2.10 - Alpha 21264/OSF1 V4.0 - SGI R10000/IRIX 6.5 (both using 32- and 64-bit limbs) - Sun UltraSparc/Solaris 2.6 - HP 9000/HP-UX A.09.05 - Pentium/Windows with Cygnus compiler - -Known problems. -=============== - -1) On some architectures (for example Alpha/OSF), the default 'make' command - crashes in step 3. GNU make is preferred. - -2) Under HP-UX and Pentium/Linux, don't use the -pedantic option, otherwise - gcc complains with the longlong.h file from GMP. - -3) On the Alpha, the test file for the square root (tsqrt) may produce - errors as follows: - - libm.a differs from mpfr_sqrt for a=9.89438396044940260000e-134, rnd_mode=2 - libm.a gives 3.14553397063986620000e-67, mpfr_sqrt gives 3.14553397063986680000e-67 (1 ulp) - libm.a differs from mpfr_sqrt for a=7.86528588050363750000e+31, rnd_mode=1 - libm.a gives 8.86864469944739500000e+15, mpfr_sqrt gives 8.86864469944739400000e+15 (-1 ulp) - - Also, Linux on Alpha is known to have problems with IEEE conformance. See - http://www.linux.org.uk/VERSION/relnotes.2211.html. - - In most cases, as above, the error comes from the libm.a. On Alpha/Linux, - which is known to have a bad libm.a, you may even find errors in the - addition or multiplication. - - +AUTHORS - the authors of the library +BUGS - bugs in MPFR - please read this file! +COPYING - the GNU General Public License, version 2 +COPYING.LIB - the Gnu Lesser General Public License, version 2.1 +ChangeLog - the log of changes +INSTALL - how to install MPFR (see also mpfr.texi) +Makefile* - files for building the library +NEWS - new features with respect to previous versions +README - this file +TODO - what remains to do (any help is welcome!) +VERSION - version of MPFR (next release version if taken from CVS) +ac*.m4 - automatic configuration files +*.c - source files +configure* - configuration files +install* - installation files +missing - auxiliary installation file +mkinst* - auxiliary installation file +mpf2mpfr.h - header file for compatibility with MPF +mpfr.h - external header file for MPFR +mpfr-impl.h - internal header file for MPFR +mpfr-math.h - another internal header file for MPFR +mpfr-test.h - header file for test files +mpfr.info - info file for MPFR +mpfr.texi - texinfo documentation for MPFR +tests/ - test directory +texinfo.tex - TeX macros to handle mpfr.texi
