.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 
.SH "Constructor & Destructor Documentation"
.PP 
.SS "QwtPointPolar::QwtPointPolar ()\fC [inline]\fP"
Constructs a null point, with a radius and azimuth set to 0\&.0\&. 
.PP
\fBSee also:\fP
.RS 4
QPointF::isNull() 
.RE
.PP

.SS "QwtPointPolar::QwtPointPolar (double azimuth, double radius)\fC [inline]\fP"
Constructs a point with coordinates specified by radius and azimuth\&.

\fBParameters:\fP
.RS 4
\fIazimuth\fP Azimuth 
.br
\fIradius\fP Radius 
.RE

.PP 
.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\&.
.PP
\fBReturns:\fP
.RS 4
Normalized point 
.RE

.SS "bool QwtPointPolar::operator!= (const \fBQwtPointPolar\fP & other) const"
Compare 2 points
.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)\&.
.PP
\fBReturns:\fP
.RS 4
True if the point is not equal to other; otherwise return false\&.
