jx+yjx+j*y
j in place of the character i as the imaginary unit.
As the basic complex unit sqrt(-1), j is used to enter complex numbers. Since j is a function, it can be overridden and used as a variable, if desired. Thus, you can still use j as an index in for loops, etc.
You can also use the character j without a multiplication sign as a suffix in forming a numerical constant.
Z = 2+3jZ = x+j*yZ = r*exp(j*theta)
