* ext/bigdecimal/bigdecimal.c (GetVpValueWithPrec):
treat 0.0 and -0.0 of floating-point numbers specially for an optimization
and to correctly propagate its signbit to the result.
[Bug #9214] [ruby-core:58858]
* test/bigdecimal/test_bigdecimal.rb: add tests case for the above change.
* test/bigdecimal/test_bigdecimal_util.rb: ditto.
