* complex.c (nucomp_div): now behaves as quo.

Browse source 
* complex.c (nucomp_s_generic_p): has been removed.

	* complex.c (nucomp_to_s): adopts new form.

	* complex.c (nucomp_inspect): ditto.

	* complex.c (string_to_c_internal): ditto and supports polar form.

	* complex.c (rb_complex_polar): new.

	* rational.c (nurat_to_s): did not canonicalize.
	
	* rational.c (nurat_inspect): adopts new form.
	
	* rational.c (string_to_r_internal): ditto.

	* include/ruby/intern.h: added a declaration.

	* lib/complex.rb: added an obsolate class method.

	* lib/cmath.rb: use scalar? instead of generic?.
