Complex numbers in the calculator can be entered in either of the two
Cartesian representations, namely, x+iy, or (x,y). The results in the calculator
will be shown in the ordered-pair format, i.e., (x,y). For example, with the
calculator in ALG mode, the complex number (3.5,-1.2), is entered as:
„Ü3.5‚í\1.2`
A complex number can also be entered in the form x+iy. For example, in ALG
mode, 3.5-1.2i is entered as:
3.5 -1.2*„¥`

entered, in the opposite order as the ALG mode exercise).
The resulting RPN screen will be:
