Using mathematical functions
(x+y*i), where x is the real part and y is the imaginary
Argument. Finds the angle defined by a complex number.
Inputs and outputs use the current angle format set in
ARG(3+3*i) returns 45 (Degrees mode)
Complex conjugate. Conjugation is the negation (sign
reversal) of the imaginary part of a complex number.
CONJ(3+4*i) returns (3-4*i)
Imaginary part, y, of a complex number, (x+y*i).
IM(3+4*i) returns 4
Real part x, of a complex number, (x+y*i).
RE(3+4*i) returns 3
The constants available from the Math Functions menu
are mathematical constants. These are described in this
section. The HP 39gII has two other menus of constants:
program constants and physical constants. The physical
constants are described further on in this chapter, while
the program constants are described in the programming
Natural logarithm base. Internally represented as
