78<span class="c"># These routines need work for +/- formatting::</span>
79<span class="c"># - pm formats are not rigorously tested</span>
80<span class="c"># - pm formats do not try to align the scale to multiples of 1000</span>
81<span class="c"># - pm formats do not try to align the value scale to uncertainty scale</span>
82
83<span class="c"># Coordinating scales across a set of numbers is not supported.  For easy</span>
84<span class="c"># comparison a set of numbers should be shown in the same scale.  One could</span>
85<span class="c"># force this from the outside by adding scale parameter (either 10**n, n, or</span>
86<span class="c"># a string representing the desired SI prefix) and having a separate routine</span>
87<span class="c"># which computes the scale given a set of values.</span>
88
89<span class="c"># Coordinating scales with units offers its own problems.  Again, the user</span>
90<span class="c"># may want to force particular units.  This can be done by outside of the</span>
91<span class="c"># formatting routines by scaling the numbers to the appropriate units then</span>
92<span class="c"># forcing them to print with scale 10**0.  If this is a common operation,</span>
93<span class="c"># however, it may want to happen inside.</span>
94
95<span class="c"># The value e&lt;n&gt; is currently formatted into the number.  Alternatively this</span>
96<span class="c"># scale factor could be returned so that the user can choose the appriate</span>
97<span class="c"># SI prefix when printing the units.  This gets tricky when talking about</span>
98<span class="c"># composite units such as 2.3e-3 m**2 -&gt; 2300 mm**2, and with volumes</span>
99<span class="c"># such as 1 g/cm**3 -&gt; 1 kg/L.</span>
