Here is the link to the Wolfram Documentation for ComplexInfinity: http://reference.wolfram.com/mathematica/ref/ComplexInfinity.html
Their one line documentation is: represents a quantity with infinite magnitude, but undetermined complex phase. Everything I've tried in Wolfram returns ComplexInfinity, but I'm still not understanding why this behavior is more desirable than regular infinity. I'm fine with implementing it this way, but it would be nice to understand why this way is more correct or general, if indeed it is.
