* Fixed various bugs in mpfr_can_round_raw, which affected mpfr_can_round:vlefevre2016-09-051-0/+1
| | | | | | | | | | | | | | there could still be false positives (i.e. mpfr_can_round could say that rounding was possible while correct rounding was not guaranteed), and also false negatives, some of which could yield infinite Ziv loops in user code in practice. Added tests triggering these bugs, in particular a comprehensive test against a naive implementation. (merged changesets r10679-10686,10717-10718,10743,10746-10748,10752,10754,10756 from the trunk) git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/branches/3.1@10792 280ebfd0-de03-0410-8827-d642c229c3f4

| | | | | | | | | | | | | under Unix because the tests could yield spurious errors with Cygwin32 or other similar implementations. Moreover, such tests were used for debugging purpose or to detect potential problems in the environment, thus were not really useful for the end user. They were initially added in the win-thread-safe-dll branch (r9682, following a problem found in r9680). One alternative for checking by the MPFR developers would be to output the status of some internal macros in tversion.

* [src/sum.c] Fixed bugs in mpfr_sum, which could return wrong resultsvlefevre2016-02-221-1/+2
| | | | | | | | | | | | | | | | | | when not all the numbers have the same precision. A side effect is that this can make mpfr_sum much slower and/or take much more memory in some of such cases with the same program; this is normal and cannot easily be avoided with the current algorithm. Note: The full rewrite currently in the trunk has not been merged because this would not be a simple patch (and it is still incomplete when a number is reused as the output). [src/mpfr-impl.h] Updated the prototype of mpfr_sum_sort. Note: Since this function is used only internally and by the tests, this does not break the ABI. However the old and new tsum tests are source & binary incompatible. [tests/tsum.c] Updated the use of mpfr_sum_sort. Added a testcase.

| | | | | | | | | | | | | | MPFR is built with logging support, these two constants are used by the logging functions (via mpfr_fprintf, then mpfr_log, for the base conversion).

Otherwise the constants could be incorrect; for instance, "MPFR_LOG_ALL=1 ./tconst_pi" was failing.
