refine Integer#** and Float#**
* complex.c (rb_dbl_complex_polar): utility function, which returns more precise value in right angle cases. * bignum.c (rb_big_pow): use rb_dbl_complex_polar(). * numeric.c (rb_float_pow, fix_pow): create a Complex by polar form. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63678 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
