 <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>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>
