[Jprogramming] represention of complex numbers

[Kip Murray]

There is no global setting, but you can use monadic *. .  From the Dictionary entry,

*.y is a two-element list of the length and angle (in radians) of the hypotenuse 
of a triangle with base and altitude equal to the real and imaginary parts y . 
For example, *. 3j4 is 5 0.927295.

Also, click on Constants on the Voc help page.  Finally, check out dyadic o. .
