Subject: [Boost-commit] svn:boost r83335 - in trunk/boost/multiprecision: . detail
From: e_float_at_[hidden]
Date: 2013-03-06 16:26:02
Author: christopher_kormanyos
Date: 2013-03-06 16:26:01 EST (Wed, 06 Mar 2013)
New Revision: 83335
URL: http://svn.boost.org/trac/boost/changeset/83335
Log:
Preliminary preparations for cpp_bin_float. Moved the rebind and dynamic_array structures from cpp_dec_float.hpp to separate files in /detail.
Added:
trunk/boost/multiprecision/detail/dynamic_array.hpp (contents, props changed)
trunk/boost/multiprecision/detail/rebind.hpp (contents, props changed)
