position (x,y) as member data and methods which operate on this position. The standard arithmetic operators are overloaded and can thus be applied to positions (x,y). It is also possible to represent a position in polar coordinates (r,phi), since the class contains a method to convert these into cartesian coordinates (x,y). <p><p>Definition at line <a class="el" href="Geometry_8h-source.html#l00098">98</a> of file <a class="el" href="Geometry_8h-source.html">Geometry.h</a>.<hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="VecPosition::VecPosition"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> VecPosition::VecPosition </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">double </td> <td class="mdname" nowrap> <em>x</em> = 0, </td> </tr> <tr> <td></td> <td></td> <td class="md" nowrap>double </td> <td class="mdname" nowrap> <em>y</em> = 0, </td> </tr> <tr> <td></td> <td></td> <td class="md" nowrap><a class="el" href="Geometry_8h.html#a19">CoordSystemT</a> </td> <td class="mdname" nowrap> <em>cs</em> = CARTESIAN</td> </tr> <tr> <td></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Constructor for the VecPosition class.
