Imaginary unit



Use 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.
