One–Number Functions
To use a one–number function (such as
,
,
?
,
=
,
¹ \
,
¹ @
,
º
g
,
¹ *
,
m
or
z
)
1. Key in the number. ( You don't need to press
Ï
.)
2. Press the function key. (For a shifted function, press the appropriate
¹
or
º
shift key first.)
For example, calculate 1/32 and
84.148
. Then square the last result and
change its sign.

Negation of 148.8400.
The one–number functions also include trigonometric, logarithmic,
hyperbolic, and parts–of–numbers functions, all of which are discussed in
chapter 4.
Two–Number Functions
In RPN mode, to use a two–number function (such as
Ù
,
Ã
,
¸
,
¯
,
)
,
¹ b
,
º `
,
'
,
¹ x
,
¹ {
,
m
or
º p
):
1. Key in the first number.
2. Press
Ï
to separate the first number from the second.
3. Key in the second number. (Do not press
Ï
.)
4. Press the function key. (For a shifted function, press the appropriate shift key
first.)
