| | | | | | | + You can compile MPFR without gmp internal files (ie gmp-impl.h, gmp-mparam.h, and config.h). You only need gmp.h and libgmp.a. But you can still compile with GMP internal files (configure detects them). git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@2665 280ebfd0-de03-0410-8827-d642c229c3f4

* Macros MPFR_EXP_INVALID (invalid exponent value) and MPFR_EXP_CHECKvlefevre2003-05-221-4/+4
| | | | | | | | | | | | added. Code update to use MPFR_GET_EXP and MPFR_SET_EXP instead of MPFR_EXP to allow more bug detection related to special values. Macros MPFR_SET_NAN, MPFR_SET_INF, MPFR_SET_ZERO and MPFR_INIT set the exponent of the number to MPFR_EXP_INVALID if MPFR_EXP_CHECK is defined. Compile with -DMPFR_EXP_CHECK and make check to see the potential problems; currently, 40 of 76 tests fail. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@2301 280ebfd0-de03-0410-8827-d642c229c3f4
