* ext/bigdecimal/bigdecimal.c (GetVpValueWithPrec): replace the algorithm for
coercing from a Rational to stop requiring "bigecimal/util.rb".
[ruby-core:34318]
* ext/bigdecimal/bigdecimal.c (GetVpValue): refactoring.
* ext/bigdecimal/bigdecimal.c (BigDecimal_new): support instantiation from a
Rational.
* test/bigdecimal/test_bigdecimal.rb (test_global_new_with_rationao): add a
test for the above change.
* test/bigdecimal/test_bigdecimal.rb (test_new_with_rationao): ditto.
