| 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. |
