Description
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 electronic engineering).
Application of the →NUM
operator returns the complex number (0,1)
in rectangular format.
Compatibility
j
is specific to newRPL and has no direct equivalent in userRPL.
Usage
Input
« 6 SETPREC j DUP →NUM »
Output
4: 3: 2: j 1: (0,1) …………………………………………………………………………………………………………
