.SH "Detailed Description"
.PP 
A point in polar coordinates. 

In polar coordinates a point is determined by an angle and a distance. See http://en.wikipedia.org/wiki/Polar_coordinate_system

.PP 
.SS "double QwtPointPolar::azimuth () const\fC [inline]\fP"
.PP
Returns the azimuth. 
.SS "bool QwtPointPolar::isNull () const\fC [inline]\fP"
.PP
Returns true if \fBradius()\fP >= 0.0. 
.SS "bool QwtPointPolar::isValid () const\fC [inline]\fP"
.PP
Returns true if \fBradius()\fP >= 0.0. 
.SS "\fBQwtPointPolar\fP QwtPointPolar::normalized () const"Normalize radius and azimuth
.PP
When the radius is < 0.0 it is set to 0.0. The azimuth is a value >= 0.0 and < 2 * M_PI. 
.SS "bool QwtPointPolar::operator!= (const \fBQwtPointPolar\fP &other) const"Returns true if point1 is not equal to point2; otherwise returns false.
.PP
Two points are equal to each other if radius and azimuth-coordinates are the same. Points are not equal, when the azimuth differs, but other.azimuth() == \fBazimuth()\fP % (2 * PI).
