The j function pushes on the stack a symbolic representation of the imaginary unit $j=\sqrt{-1}$.

j provides a convenient alias of i for those applications where the latter might be confused with the i variable (usually Electronics).

Application of the →NUM operator returns the complex number (0, 1) in rectangular format.

This command is new in newRPL and does not exist in userRPL.

The following program

« 6 SETPREC
  j DUP
  →NUM
»

will result in

2:                             j
1:                         (0,1)
