DirectedInfinity

FilledSmallSquareDirectedInfinity[ ] represents an infinite numerical quantity whose direction in the complex plane is unknown.

FilledSmallSquareDirectedInfinity[z] represents an infinite numerical quantity that is a positive real multiple of the complex number z.

FilledSmallSquare You can think of DirectedInfinity[z] as representing a point in the complex plane reached by starting at the origin and going an infinite distance in the direction of the point z.

FilledSmallSquare The following conversions are made:

FilledSmallSquare Certain arithmetic operations are performed on DirectedInfinity quantities.

FilledSmallSquare In OutputForm, DirectedInfinity[z] is printed in terms of Infinity, and DirectedInfinity[ ] is printed as ComplexInfinity.
