j x+yj x+j*yUse the character
j in place of the character i, if desired, as the imaginary unit.
As the basic imaginary unit sqrt(-1), j is used to enter complex numbers. Since j is a function, it can be overridden and used as a variable. This permits you to use j as an index in for loops, etc.
It is possible to use the character j without a multiplication sign as a suffix in forming a numerical constant.

conj Complex conjugate
