t types, but with a 113 bit mantissa, and compatible
          with FORTRAN's 128-bit QUAD real.

          All the usual standard library and <code class="computeroutput"><span class="identifier">numeric_limits</span></code>
          support are available, performance should be equivalent to the underlying
          native types: for example the LINPACK benchmarks for GCC's <code class="computeroutput"><a class="link" href="float128.html" title="float128">float128</a></code>
          and
