<h1 style="margin-top:0px">hgeVector Operators</h1>
<p>
The following operators are defined for <b>hgeVector</b> class:
<p>
<pre>
hgeVector   operator- (const hgeVector &v);
hgeVector   operator+ (const hgeVector &v);
hgeVector   operator* (float scalar);
hgeVector   operator- ();

hgeVector&  operator-= (const hgeVector &v);
hgeVector&  operator+= (const hgeVector &v);
hgeVector&  operator*= (float scalar);

bool        operator== (const hgeVector &v);
bool        operator!= (const hgeVector &v);

float       operator^ (const hgeVector &v, const hgeVector &u);
float       operator% (const hgeVector &v, const hgeVector &u);
</pre>
<p>
So, you can use <b>hgeVector</b> objects in expressions like
<br><br>
<b>vector1</b> = -<b>vector2</b>;<br>
<b>vector1</b> = <b>vector2</b> + <b>vector3</b> * 0.5f;<br>
if(<b>vector1</b> != <b>vector2</b>) <b>vector1</b> += <b>vector3</b>;<br>
<br>
<b>angle</b> = <b>vector1</b> ^ <b>vector2</b>;<br>
<b>dot_product</b> = <b>vector1</b> % <b>vector2</b>;<br>
</p>
