New Revision: 76433
URL: http://svn.boost.org/trac/boost/changeset/76433
Log:
Update docs to include fixed_int.hpp.
Remove 64-bit versions of fixed_int typedefs - better to use boost::int64_t instead.
Added:
sandbox/big_number/libs/multiprecision/example/fixed_int_snips.cpp (contents, props changed)

+The `fixed_int` backend is used via one of the typedefs `boost::multiprecision::mp_uint128_t`, `boost::multiprecision::mp_uint256_t`,
+`boost::multiprecision::mp_uint512_t`, `boost::multiprecision::mp_int128_t`, `boost::multiprecision::mp_int256_t`
+or `boost::multiprecision::mp_int512_t`. It provides both signed and unsigned integer types with a fixed precision
+and modular arithmetic with a 2's complement representation for negative values. In other words it's designed to work just
+like a typical built in integer type, but with larger precision.
