the PDF, or otherwise calculating, zero is not the
          most useful value for the lower limit of supported, as we discovered. So
          for this, and similar distributions, we have decided it is most numerically
          useful to use the closest value to zero, min_value, for the limit of the
          supported range. (The <code class="computeroutput"><span class="identifier">range</span></code>
          remains from zero, so you will still get <code class="computeroutput"><span class="identifier
