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.

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.
