archCalc 1.9.3
archCalc is a mixed unit decimal and fraction calculator. It allows one
to enter dimensions in standard english and metric units of measurement,
perform basic calculations, convert between units, keep track of a
series of operations, and take notes on results.
archCalc works as a standalone calculator or in conjunction with other
programs, calculating stair risers in CAD software, or aiding in
takeoffs with a spreadsheet. archCalc floats above applications
allowing one to work with it as if it were a part of the active
application.

Calc 1.14
Calc is easy to use, just enter your calculation in the lower text field
and hit return to get the result in the upper textfield. The result of
every calculation is stored in a variable (r0 ... r<n>). These variables
can be used in later calculation. The ArrowUp and ArrowDown keys
allows you to browse through calculation history.

Calcline 1.5
Calcline is a utility that lets you digit mathematical expressions and have the result available in a snap.
It was thought to replace the standard calculator based on a metaphor that is simply out of date.
We made a great effort to make it simple to be used by everyone.
Calcline starts as a small window utility.
It is very simpleto use it. Just insert a mathematical expression to evaluate and Calcline will do the work.
Expression can be very easy such as:
42+110+25+44+32+25
This is really a simple task and in that way you are using Calcline as a substitute of the standard calculator available on any Mac starting from a 128k Mac available from 1984.
Expressions can also be much more complex, with a lot of nested parenthesis and functions.
For example you can type an equation such as:
23*(cos(1.875)0.0025*0.001)+tan(0.258+0.025*2)
and Calcline will solve it in a snap.
Using trigonometric formula you can use the Deg or the Rad modality as
in any advanced calculator. You can insert functions using the f popup
immediately above the input field without having to remember it.
Calcline can be used in this compact view or using an extended view.

Calq 1.4.6
Calq is an easy to use, on demand calculator. The idea behind Calq is to
have a calculator handy when you need it do some basic calculations
quickly. It's there when you need it, and it's not in the way when you
don't need it.
The intended way to use Calq is by adding it as a startup item in your
account preferences. But off course you can also start Calq by
doubleclicking the icon. The first time you start Calq you will be
presented with a little welcome message, and after that the preference
window is shown, so you can set it up to your liking. After confirming
the preferences by clicking OK, you notice is that nothing seems to
happening, because no icon appears in the dock. But don't worry, Calq is
now sitting in the background waiting to be activated when you need it.
After Calq is started, you can activate it by using a hotkey
combination. When Calq is activated it will present a small window that
allows you to do calculations through the keyboard. The window will stay
up as long is keyboard activity is sensed. If you don't type anything
for a few seconds Calq will hide itself again until you activate it
again. Calq will also hide itself immediately if you activate another
application.

second.
All of this power is available, yet many early Mac OS Xready machines
do not have even a basic scientific calculator included with the
operating system. This is where EdenMath comes in.

R 2.8.1
R is a language and environment for statistical computing and graphics.
It is a GNU project which is similar to the S language and environment
which was developed at Bell Laboratories (formerly AT&T, now Lucent
Technologies) by John Chambers and colleagues. R can be considered as a
different implementation of S. There are some important differences, but
much code written for S runs unaltered under R.
R provides a wide variety of statistical (linear and nonlinear
modelling, classical statistical tests, timeseries analysis,
classification, clustering, ...) and graphical techniques, and is highly
extensible. The S language is often the vehicle of choice for research
in statistical methodology, and R provides an Open Source route to
participation in that activity.
One of R's strengths is the ease with which welldesigned
publicationquality plots can be produced, including mathematical
symbols and formulae where needed. Great care has been taken over the
defaults for the minor design choices in graphics, but the user retains
full control.

wish that you could make a picture of the result (see above) with one keystroke?
need to know whether a set of random variates was truly Gaussian? Uniform? Gumbel? ...
think that a combination of two distributions might be the real answer?
try to find the formula for the mode of some density function?
require millions of variates from a specified distribution?

rpnCalc is a reverse polish notation (RPN) calculator. The stack

How it works: Entry is the same as on a desktop adding machine.
Enter the number first, then press either add (+) or subtract (). (Multiply and divide don't work yet.)
The Enter key on the keypad acts as the + button on an adding machine.
Pressing clear (Num Lock) clears the current entry.
Pressing = totals the tape, and the tape will clear the next time you enter a number.
Pressing + or  without entering a number also totals the tape.
Use the Info button to toggle between floating and +2 decimal operation.
