Detailed Description

A double that's an angle.

An IpeAngle is really nothing more than a double. Having a separate type is sometimes useful, for instance in the IpeVector constructor, and this class serves as the right place for a few utility functions. It also makes it clear whether a value is in radians or in degrees.

Constructor & Destructor Documentation

IpeAngle::IpeAngle (   )  [inline, explicit]
 

Construct uninitialized angle.

IpeAngle::IpeAngle (  double  alpha  )  [inline]
 

Construct an angle (in radians).

Member Function Documentation

IpeAngle IpeAngle::Degrees (  double  alpha  )  [inline, static]
 

Construct an angle in degrees.

IpeAngle::operator double (   )  const [inline]
 

Return value (in radians).

IpeAngle IpeAngle::Normalize (  double  lowlimit  ) 
 

Normalize the value to the range lowlimit .. lowlimit + 2 pi.

This IpeAngle object is modified, a copy is returned.

bool IpeAngle::LiesBetween (  IpeAngle  small,
IpeAngle  large
)  const
 

When considering the positively oriented circle arc from angle small to large, does it cover this angle?
