<div class="RenoIncludeDIV"><div class="RenoAutoDIV"><h3>Scalar Requirements</h3>
|
|
</div>
|
|
<p>A valid scalar type <i>S</i> must have accessible destructor, default constructor, copy constructor and assignment operator, and must support the following operations:</p>
|
|
<pre>S operator*( S, S );
|
|
S operator/( S, S );
|
|
S operator+( S, S );
|
|
S operator-( S, S );
|
|
|
|
S & operator*=( S &, S );
|
|
S & operator/=( S &, S );
|
|
S & operator+=( S &, S );
|
|
S & operator-=( S &, S );
|
|
|
|
bool operator==( S, S );
|
|
bool operator!=( S, S );</pre>
|
|
<p>In addition, the expression <i>S(0)</i> should construct a scalar of value zero, and <i>S(1)</i> should construct a scalar of value one -or- the <i><span class="RenoLink"><a href="scalar_traits.html">scalar_traits</a></span></i> template must be specialized appropriately.</p>
