Use the character
j in place of the character
i, if desired, as the imaginary unit.
As the basic imaginary unit
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.
