Since the imaginary and real parts of a complex number are entered and stored separately, you can easily work with or alter either part by itself.

Always enter the imaginary part (the y–part)of a number first. The real portion of the result (zx) is displayed on the second line; the imaginary portion (zy) is displayed on the first line. (For two–number operations, the first complex number, z1, is replicated in the stack's Z and T registers.)

Complex Operations

Use the complex operations as you do real operations, but precede the operator with {G.

To do an operation with one complex number:

1.Enter the complex number z, composed of x + i y, by keying in y ‘x.

2.Select the complex function.
