

is the prefix for hyperbolic functions, as
 
is for their inverses (see
SINH, COSH, TANH, ASINH, ACOSH, and ATANH). In analogy,
 
stands
for ASIN, etc.


is the prefix for five immediate conversions:

trailed by

,

,

,

, or

will convert x , i.e. the value currently displayed. The
respective function names all begin with

. And furthermore,

is employed
for indirect addressing.


calls

REC, converting polar to rectangular coordinates in 2d. So the pair
 
takes care of the two classic coordinate transformations.


is mainly employed as a prefix for calling complex operations. See the re-
spective paragraph below for more.


and

enter the fraction mode for proper and improper fractions, re-
spectively (see PROFRC and IMPFRC).


and

represent the two time modes, where

stands for decim-
al hours, but also for floating point numbers in general (see DECM).


enters alpha mode , while

,

,

, or

will enter integer modes for
calculating with binary, octal, decimal, or hexadecimal numbers
(see BASE…).

 
calls x
 α and α 
x, respectively.


calls x! in default floating point mode,

toggles radix marks by calling
RDX , or RDX . ,

toggles programming mode, and

calls ABS.
These were all the special labels featured. You will find each and every command
provided on your WP 34S below in the
index of operations for your reference, to-
gether with the necessary individual explanation.
In four decades of pocket calculators, a wealth of nice to sophisticated application
examples were invented and described by different authors
– more and better than
we can ever create ourselves. Also it is not our intention to copy these old examples.
Instead, we recommend the DVD mentioned
above once more: it contains all the us-
er guides, handbooks, and manuals of vintage Hewlett Packard calculators. Be as-
sured that almost everything described there for any scientific calculator can be done
on your WP 34S as well, just significantly faster.
Let us return to our introductory example for two remarks:
1. There is no need to enter any units. The example will work with meters as
well, for example.
2. Although we entered integer numbers only for both sides of our little ground,
the calculation was executed in default floating point mode of your WP 34S.
This calculator mode allows for decimal fractions of e.g. feet in input and out-
put as well. Another mode lets you key in proper fractions like e.g. 6 ¼.
Before you suffer from feet fractions, however, we want to briefly show you some ad-
ditional modes your WP 34S features (you will find a complete list of all modes pro-
vided in a separate chapter further below).
