Imaginary unit



As the basic imaginary unit sqrt(-1), i is used to enter complex numbers. Since i is a function, it can be overridden and used as a variable. This permits you to use i as an index in for loops, etc.

If desired, use the character i without a multiplication sign as a suffix in forming a complex numerical constant.

You can also use the character j as the imaginary unit.
