| 20 | </div> | |
| 21 | <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> | |
| 22 | <pre>S operator*( S, S ); | |
| 23 | S operator/( S, S ); | |
| 24 | S operator+( S, S ); | |
| 25 | S operator-( S, S ); | |
| 26 | ||
| 27 | S & operator*=( S &, S ); | |
| 28 | S & operator/=( S &, S ); | |
| 29 | S & operator+=( S &, S ); | |
| 30 | S & operator-=( S &, S ); | |
| 31 | ||
| 32 | bool operator==( S, S ); | |
| 33 | bool operator!=( S, S );</pre> | |
| 34 | <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> | |
