* ext/bigdecimal/bigdecimal.c (Init_bigdecimal, rmpd_set_thread_local_exception_mode, VpGetException, VpSetException): thread-local exception mode.
* ext/bigdecimal/bigdecimal.c (Init_bigdecimal, rmpd_set_thread_local_precision_limit, VpGetPrecLimit, VpSetPrecLimit): thread-local precision limit. * ext/bigdecimal/bigdecimal.c (Init_bigdecimal, rmpd_set_thread_local_rounding_mode, VpGetRoundMode, VpSetRoundMode, VpException, VpInternalRound): thread-local rounding mode. * ext/bigdecimal/bigdecimal.c (BigDecimal_mode, BigDecimal_round, VpIsRoundMode, VpGetRoundMode, VpSetRoundMode, VpActiveRound, VpMidRound, VpLeftRound), ext/bigdecimal/bigdecimal.h: use unsigned short for rounding mode. * test/bigdecimal/test_bigdecimal.rb (test_mode): add test for setting rounding mode. * test/bigdecimal/test_bigdecimal.rb (test_thread_local_mode): add test for setting mode thread-locally. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@29099 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
