Member Function Documentation

double geometric::circle::area

(

)

const

Returns the area occupied by the circle.

Definition at line 36 of file circle.cpp.

References PI_APPROX, and square().

double geometric::circle::circumference

(

)

const

Returns the perimeter for the circle.

The circumference is the length of a virtual string around the circle.

Definition at line 40 of file circle.cpp.

References PI_APPROX.

double geometric::circle::diameter

(

)

const

Returns the length of the circle's bisecting line.

This is the length of a line segment that is circumscribed by the circle and which passes through the center of the circle.

Definition at line 38 of file circle.cpp.

bool geometric::circle::inside

(

const cartesian_point &

where

)

const

Returns true if the point is inside the circle.

Definition at line 49 of file circle.cpp.

References geometric::point< numeric_type >::distance().

cartesian_point geometric::circle::location

(

const double_angle &

where

)

const

Returns the point on the circle that is at the angle "where".

Definition at line 42 of file circle.cpp.

References geometric::angle< contents >::get(), and geometric::angle< double >::RADIANS.

Referenced by dimensions().

cartesian_rectangle geometric::circle::dimensions

(

)

const

Returns a bounding box around the circle.

Reimplemented in ring.

Definition at line 55 of file circle.cpp.

References location(), PI_APPROX, geometric::point< numeric_type >::x(), and geometric::point< numeric_type >::y().

double geometric::circle::radius

(

)

const

Half of the circle's diameter.

Definition at line 69 of file circle.cpp.

void geometric::circle::radius

(

double

to_set

)

Sets the radius of the circle.

Definition at line 71 of file circle.cpp.

cartesian_point geometric::circle::center

(

)

const

The point at the center of the circle.

Definition at line 73 of file circle.cpp.

void geometric::circle::center

(

const cartesian_point &

to_set

)

Resets the circle's center.
