 <p>A wrapper to represent absolute units (points rather than vectors). Intended originally for temperatures, this class implements operators for absolute units so that addition of a relative unit to an absolute unit results in another absolute unit : absolute&lt;T&gt; +/- T -&gt; absolute&lt;T&gt; and subtraction of one absolute unit from another results in a relative unit : absolute&lt;T&gt; - absolute&lt;T&gt; -&gt; T. </p>

 <p>Reduce dimension list to cardinal form. This algorithm collapses duplicate base dimension tags and sorts the resulting list by the tag ordinal value. Dimension lists that resolve to the same dimension are guaranteed to be represented by an identical type.</p>
 <p>The argument should be an MPL forward sequence containing instances of the <code class="computeroutput">dim</code> template.</p>
 <p>The result is also an MPL forward sequence. It also supports the following metafunctions to allow use as a dimension.</p>

 <p>This is an implementation of a compile time rational number, where <code class="computeroutput">static_rational&lt;N,D&gt;</code> represents a rational number with numerator <code class="computeroutput">N</code> and denominator <code class="computeroutput">D</code>. Because of the potential for ambiguity arising from multiple equivalent values of <code class="computeroutput"><a class="link" href="static_rational.html" title="Class template static_rational">static_rational</a></code> (e.g. <code class="computeroutput">static_rational&lt;6,2&gt;==static_rational&lt;3&gt;</code>), static rationals should always be accessed through <code class="computeroutput">static_rational&lt;N,D&gt;::type</code>. Template specialization prevents instantiation of zero denominators (i.e. <code class="computeroutput">static_rational&lt;N,0&gt;</code>). The following compile-time arithmetic operators are provided for <a class="link" href="static_rational.html" title="Class template static_rational">static_rational</a> variables only (no operators are defined between long and <a class="link" href="static_rational.html" title="Class template static_rational">static_rational</a>):</p>
