endian.
(rb_quad_pack): use quad_buf_complement. don't raise for large
values.
(rb_quad_unpack): use quad_buf_complement.
(quad_buf_complement): new function extracted frm rb_quad_pack.

denote that #to_i raises FloatDomainError for Inf and NaN.
* ext/bigdecimal/bigdecimal.c (BigDecimal_to_i): fast #to_i using
BigDecimal_split().
* bignum.c (conv_digit): use faster ISDIGIT() assuming ASCII.

* bignum.c (big2dbl): truncates zero digits to get rid of possible
underflow.

can be converted to float properly.
* numeric.c (fix_fdiv): calls rb_big_fdiv when the given second
argument is a bignum.
* rational.c (nurat_fdiv): should calculate Float(x/y), not
Float(x)/Float(y).

* bignum.c (bigsqr): call bigmul0(x, x) because it is faster than the
original bigsqr at this point.
* bignum.c (rb_big_pow): a value returned from bigsqr is already
truncated.

* rational.c: ditto.
* bignum.c (rb_big_pow): bignum**bignum - should calculate without
rational.
* lib/complex.rb: should override Math module at most once.
* lib/mathn.rb: requires 'cmath' directly.
