Icon 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.

Icon 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 double-clicking 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.

Icon 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, time-series 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 well-designed publication-quality 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.

Did you ever have to fit your data to a function that was not necessarily a straight line? believe that you already knew some of the parameters? wonder if the optimum fit were statistically acceptable? want the minimum average deviation instead of least-squares? desire robust confidence intervals for the fitted parameters? 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? give up on any of these and settle for second best?
Well, now you don't have to. Regress+ will do all that and more ...

rpnCalc is a reverse polish notation (RPN) calculator. The stack behavior is based, rather loosely, on the HP-28S. I originally wrote it because the battery on my HP-28S died and I needed a calculator. Yes, I suppose I could have bought a new battery. But instead I wrote an HTML/Javascript/CSS RPN calculator; partly out of need, and partly as an exercise in Javascript.

Icon Tape Calculator 1.0

This program is designed to replace a standard desktop adding machine/calculator, allowing 10-key touch number entry. Use it for high-speed adding and subtracting of numbers.
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.
