Section 11: Calculating With Complex Numbers 129
Entering a Pure Imaginary Number
There is a shortcut for entering a pure imaginary number into the X-
register when you are already in Complex mode: key in the (imaginary)
number and press ´ }.
Example: Enter 0 + 10i (assuming the last function executed was not −
or `.

displayed real X-register
and zero into the
imaginary X-register.

shows that the number
in the real X-register is
zero—as it should be for
a pure imaginary
number.
The operation of the real and imaginary stacks during this process is
illustrated below. (Assume the stack registers contain the numbers
resulting from the preceding examples.)
