Operations with Comb Numbers
The HP 32SII can use complex numbers in the form
x
+
iy
.
It has operations for complex arithmetic (+, –,
×
,
÷
), complex trigonometry (sin,
cos, tan), and the mathematics functions –z, 1/z,
2
1
z
z
,
ln z, and e
z
. (where
z
1
and
z
2
are complex numbers).
To enter a complex number:
1. Type the imaginary part.
2. Press

.
3. Type the real part.
Complex numbers in the HP 32SII are handled by entering each part
(imaginary and real) of a complex number as a separate entry. To enter two
complex numbers, you enter four separate numbers. To do a complex
operation, press
z F
before the operator. For example, to do
(2 + i 4) + (3 + i 5),
press 4

2

5

3
z F 
.
The result is 5 + i 9. (Press
Z
to see the imaginary part.)
The Complex Stack
The complex stack is really the regular memory stack split into two double
registers for holding two complex numbers, z
1X
, + i z
1y
and z
2X
+ i z
2y
