One–Number Functions

To use a one–number function (such as , #, !,{@, {$, K,{,Qor ^)

1.Key in the number. ( You don't need to press ‘.)

2.Press the function key. (For a shifted function, press the appropriate {or shift key first.)

For example, calculate 1/32 and 148.84 . Then square the last result and change its sign.

Keys:	Display:	Description:
32	_	Operand.
	)	Reciprocal of 32.
148.84 #	)	Square root of 148.84.
!	)	Square of 12.2.

^.) 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 ›, …, z, q, ,

{F, D,, {\, {_, Qor T):

1.Key in the first number.

2.Press ‘to separate the first number from the second.

3.Key in the second number. (Do not press ‘.)

4.Press the function key. (For a shifted function, press the appropriate shift key first.)

Note	In RPN mode, type in both numbers (separate them by selecting
	‘) before selecting a function key.
