A quick websearch will give many guides and tutorials. You don't need to learn python, just using its powerful calculation capabilities. It also has a GTK UI if you want that.Īnother neat solution is python itself if you have it on your system. It gives you a prompt and you quit it the usual way Ctrl+c (or Ctrl+d). Regarding to CLI calculators if that suits you, qalculate is as good as octave CLI can be but having way less dependencies. Octave is good, but it has an awful lot of dependencies for just a calculator, specially if you don't use Qt5 in advance or you don't plan to use its GUI. I have to agree, Calculators use to suck.
Speedcrunch rpn windows#
Just today I had to boot Windows so I could paste a LONG list of numbers into it's calculator for simple addition purposes, and I'd really like to quit needing Windows completely and just stay booted up in Linux. Issuing "wine calc" in a terminal window results in,Ġ009:fixme:actctx arse_depend_manifests Could not find dependent assembly L"-Controls" (6.0.0.0)Īnyway, sorry for the off topic, but since there are some savvy Linux users here, I thought I'd ask. I tried to bring the freekin' Windows calculator over to run in Wine, but it is so entangled in the OS I don't know if that's even possible. It takes seven presses of the key for the above example, and that is a very shortened example of what I frequently need.
Speedcrunch rpn series#
Or can deal with me pasting a long series of numbers grabbed from other things I'm working on like.Īnd end up with 1,948 rather than getting a stoopid "nan" on the calculator display. What I am looking for is a calculator that can deal with a series of entries like,ĥ2.95-44.5675*125 (only a SINGLE enter key press)Īnd come back with 1,047.8125 and not -5517.9875 which is what I get if not pressing every step of the way. Note: the build directory can not be the same as the source directory.Why do all the Linux calculators suck so bad? I've searched high and low for one that can do simple stuff like the stock Windows calculator and have only found either calculators with GIANT interfaces that still do stoopid things, or smaller and more useful sized ones that still act totally stoopid and require tons of extra keystrokes to accomplish basic things. From the build directory, first run: cmake Then create a build directory (where the program will be compiled and linked).

To compile, simply extract the source tarball.
Speedcrunch rpn mac os#
CMake is available for Windows, Linux, and Mac OS X. You also need CMake (from Kitware) at least version 2.4.4. However, you need the development package as well (sometimes named as qt-devel or qt4-devel, it varies depends on the distributions). Most Linux distributions normally already package the latest version of Qt, so it is likely that you need to worry about this. You need Qt (from Trolltech) at least version 4.2 to be able to compile SpeedCrunch. The application, and Qt itself, is in the bundle represented by the icon. If you are installing SpeedCrunch from a disk image on an Apple Mac, all you need do is drag the SpeedCrunch application icon to your Applications folder. For your convenience, it is even possible to customize the font and color used for the display.ĭownload is available from, the official website. For example, just typing sin followed by Enter - likely means taking the sine of last value. Often, SpeedCrunch can still understand an incomplete expression. This means, you can still recall those calculations you have done yesterday or last week. Your expression history (maximum last 100 expressions), as well as variables you have defined, are saved between sessions. Another variable pi holds one of the most important constant in math world. There is a special variable, ans, which always holds the last calculation result. When you want to use a variable but you can not recall its exact name, use Ctrl+I to show a list of variables that you can pick easily. You can define as many variables as you want. Using assignment, such as x=0.3 means that variable named x has the value of 0.3, which you can always later on, for example sin(x). SpeedCrunch allows a variable to hold calculation result.

Advanced calculation sometimes needs memory feature. Beside standard algebraic operators like + (addition), - (substraction). If you want to reuse again the expression which you typed before, then press up and down arrow to access the expression history. And, you can quickly copy the last calculation result to the clipboard using Ctrl+R. Result is shown in the scrollable display. SpeedCrunch is easy to use, just type the expression that you want to calculate and press Enter.
