represents an infinite numerical quantity whose direction in the complex plane is unknown.
represents an infinite numerical quantity that is a positive real multiple of the complex number z.
- 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.
- The following conversions are made:
Infinity DirectedInfinity -Infinity DirectedInfinity[-1] ComplexInfinity DirectedInfinity
- Certain arithmetic operations are performed on DirectedInfinity quantities.
- In OutputForm, DirectedInfinity[z] is printed in terms of Infinity, and DirectedInfinity is printed as ComplexInfinity.
