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 It was thought to replace the standard calculator based on a metaphor that is simply out of date.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.
Calc Thingy 1.1.2 Calc thingy is completely respectable and is a wonderful tool for learning and performing daily mathematical functions. I wrote it because nothing else did what I wanted. This does, mostly. It doesn't pay my taxes by itself, but it comes close. It's as full of features as you want it to be.
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.

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.
Regress+ 2.5.3 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 leastsquares? 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 1.6.1 rpnCalc is a reverse polish notation (RPN) calculator. The stack behavior is based, rather loosely, on the HP28S. I originally wrote it because the battery on my HP28S 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.
RPN Calculator 1.9.6 RPN Calculator is a fairly robust implementation of RPN which has enjoyed moderate popularity in the Mac community. The program has benefited from 2 years of intense development followed by another year of minor improvements and bug fixes.
