Hi, I am a GSoC student and I am implementing a library to handle integral values. I want to know if exists functions to do integer rotate shifts in Boost. If it not exists I am suggesting these functions: http://svn.boost.org/svn/boost/sandbox/SOC/2010/bits_and_ints/boost/integer/... To do right and left rotation shifts. And want to know if is better to check if the length of rotation is less than the size in bits of the type. Best, -- Murilo Adriano Vasconcelos http://murilo.wordpress.com
