| 41 | <p>When <code class="computeroutput">x</code> has an indeterminate value, it outputs either the integer value 2 (if <code class="computeroutput">(out.flags() & std::ios_base::boolalpha) == 0</code> ) or the name of the indeterminate value. The name of the indeterminate value comes from the indeterminate_name facet (if it is defined in the output stream's locale), or from the get_default_indeterminate_name function (if it is not defined in the locale or if the C++ standard library implementation does not support locales).</p> |
