<p>
Boost.Integer provides integer type support, particularly helpful in generic
programming. It provides standard C99 integer types, such as might be found
in <stdint.h>, without requiring that header. It provides the means to
select an integer type based upon its properties, like the number of bits or
the maximum supported value, as well as compile-time bit mask selection. There
is a derivative of std::numeric_limits that provides integral constant expressions
for <code class="computeroutput"><span class="identifier">min</span></code> and <code class="computeroutput"><span class="identifier">max</span></code>.
Finally, it provides two compile-time algorithms: determining the highest power
of two in a compile-time value; and computing min and max of constant expressions.
