</p><p>The numbers that are supported by <span class="t-lc"><strong class="selflink">std::numpunct</strong></span> have the format described below. Here <code>digit</code> represents the radix set specified by the <code>fmtflags</code> argument value, <code>thousands-sep</code> and <code>decimal-point</code> are the results of <span class="t-lc"><a href="numpunct/thousands_sep.html" title="cpp/locale/numpunct/thousands sep">thousands_sep()</a></span> and <span class="t-lc"><a href="numpunct/decimal_point.html" title="cpp/locale/numpunct/decimal point">decimal_point()</a></span> functions respectively.
