Point Cartesian point


Superclass: Object


Defines a point on the Cartesian plane.



Creation


new(inX, inY)


defines a new point.



Accessing


x


get the x coordinate value.


y


get the y coordinate value.


x_(aValue)


set the x coordinate value.


y_(aValue)


set the y coordinate value.


set(inX, inY)


Sets the point x and y values.



Testing


== aPoint


answers a Boolean whether the receiver equals the argument.


hash


returns a hash value for the receiver.



Math


+ aPointOrScalar


Addition.


- aPointOrScalar


Subtraction.


* aPointOrScalar


Multiplication.


/ aPointOrScalar


Division.


translate(aPoint)


Addition by a Point.


scale(aPoint)


Multiplication by a Point.


rotate(angle)


Rotation about the origin by the angle given in radians.


abs


Absolute value of the point.


rho


return the polar coordinate radius of the receiver.


theta


return the polar coordinate angle of the receiver.


dist(aPoint)


return the distance from the receiver to aPoint.


transpose


return a Point whose x and y coordinates are swapped.


round(quantum)


round the coordinate values to a multiple of quantum.


trunc(quantum)


truncate the coordinate values to a multiple of quantum.



Conversion


asPoint


returns the receiver.


asComplex


returns a complex number with x as the real part and y as the imaginary part.


asString
