This is what the programmer calculator in Mac OS X looks like:Īnd this is what the scientific calculator in Mac OS X looks like:Ĭalculator RPN Mode can be accessed by hitting Command+R or by enabling it from the View menu.īoth the talking calculator and the paper tape will work with the alternate calculators as well, which can come in handy to keep track of what data you’re working with.īy the way, you can copy (and paste) anything from Calculator app in OS X too, both from the calculator and from the paper tape. The programmer calculator works with hexadecimal, decimal, binary, ascii, unicode, and the scientific calculator supports scientific notation, logarithmic, exponential, constants, exponents, fractions, roots, and all else you’d expect. Pull down the “View” menu and select either “Scientific” or “Programmer”Ĭalculator app will instantly transform into which alternate calculator you chose.Open the Calculator app from /Applications/, Spotlight, or Launchpad.
Maxima's help (which is also available from wxMaxima's help menu) will give you more information.Here’s all you need to do to switch calculator modes on the Mac: Press Shift+Enter, wait a few seconds, and you'll be ready to work.īy default, the unit package works with the basic MKS units, but if you prefer, for instance, to get N instead of kg*m/s2, you just need to type: One of the (wx)Maxima combo's most impressive features is that it works with dimension units.

On top of the full power of Maxima, wxMaxima allows you to create "notebooks" on which you write comments, keep your graphics with your math, etc. WxMaxima is a well-designed graphical frontend for Maxima that simplifies the use of many Maxima options without compromising others. Maxima is a computer algebra system (CAS) with which you can do derivatives, integrals, series, equations, eigenvectors and eigenvalues, Taylor series, Laplace and Fourier transformations, as well as numerical calculations with arbitrary precision, graph on two and three dimensions… we could fill several pages just listing its capabilities. Sometimes (OK, many times) a desktop calculator is not enough and you need more raw power. The main application is written in PyQt5, but there is also an online version written in JavaScript. Just write the starting unit and the final unit in the corresponding boxes if the units are compatible, you'll get the transformation without protest. Trying to convert from astronomical units per year into inches per second? It doesn't matter if it makes sense or not, if you need to transform a unit of any kind, ConvertAll is the tool for you. Most unit converters stop at a long list of basic units and a bunch of common combinations, but not ConvertAll. OK, it's not a "calculator," yet this simple application is incredibly useful.

Also, Qalculate! is more flexible with syntax errors, so you don't need to worry about closing all those parentheses: if there is no ambiguity, Qalculate! will give you the right answer.Īfter a long period on which the project seemed orphaned, it came back to life in 2016 and has been going strong since, with more than 10 versions in just one year. It's licensed under GPLv2 (with source code on GitHub) and offers versions for Linux and Windows, as well as a MacOS port. Have you heard of an exapascal pressure? I hadn't (the Sun's core stops at ~26 PPa), but Qalculate! has no problem understanding the meaning of 1 EPa. Its use of units is far more intuitive than SpeedCrunch's and it understands common prefixes without problem. It allows you to work with units, handle physical constants, create graphics, use complex numbers, matrices, and vectors, choose arbitrary precision, and more. The project offers a powerful library that can be used by other programs (the Plasma desktop can use it to perform calculations from krunner) and a graphical interface built on GTK3. Qalculate! (with the exclamation point) has a long and complex history. It works on Linux, Windows, and MacOS, and it's licensed under GPLv2 you can access its source code on Bitbucket. The list of available functions is really impressive. More options are available on the Configuration menu.
With the F5 key, all results will turn into scientific notation ( 1.08e9 kilo meter / hour), while with F2 only numbers that are small enough or big enough will change. It supports working with units and comes loaded with all kinds of functions.īy default, SpeedCrunch delivers its results in the international unit system, but units can be transformed with the "in" instruction.ģ*10^8 meter / second in kilo meter / hour
