Numerics are a symbolic representation of numeric values.
In many cases, but not always, an object of type <a href="Mlpost.Num.html#TYPEt"><code class="code">Num.t</code></a> is intended to be
a length in some unit. In addition, values of type <a href="Mlpost.Num.html#TYPEt"><code class="code">Num.t</code></a> may actually be
unknown to Mlpost. This is why there is no function that gives back a
<code class="code">float</code>.<br>
