* complex.c ({nucomp,numeric}_rect): new.
* complex.c: added some aliases (::rectangular, ::rect, #rectangular, #rect, #phase, #magnitude). * complex.c (string_to_c_internal): should not strip any null bytes. * rational.c (string_to_r_internal): ditto. * rational.c (i_gcd): reverted to nurat 0.0.2's one. * numeric.c: added an alias (#magnitude). * test/ruby/test_complex.rb: added assertions. * test/ruby/test_rational.rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@18925 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
