![]() A mature matrix calculator would let you use matrices about anywhere you'd use ordinary numbers, like in exp(A), sin(A^B) and so on, with A and B being matrices. However, matrix support is hardly integrated in the main workflow. Their elements might even be complex numbers (see below). Whilst SC doesn't support matrix calculations, MNM allows to deal with matrices in a dedicated drawer. There was a temptation to just stick with SC, but luckily, I went on and discovered Magic Number Machine.Ī interesting difference in SC's and MNM's feature set is matrix support. Also, it provides remarkably convenient I/O. When I found SpeedCrunch at first, I was stunned by the range of functions and constants implemented therein. ), I am looking for alternatives that actually let me calculate (correctly, that is) and maybe even provide more functionality. Since I've encountered ridiculously incorrect results with Calculator.app recently (see e. Large number of scientific constants built-in.Matrix functions including gaussian elimination, inversion, and determinants.Value memory limited only by computer memory.A graphical display that you can click on to change the entry point.A full expression history (go back to anything).Floating-point numbers, even in non-decimal radices.Hexdecimal, octal, binary, decimal, and 2's complement display. ![]() The extensive support of complex numbers and hexadecimal numbers is also a significant benefit for anyone who has to work with this type of data. "Data" drawers allow an easy way to generate statistical data, linear regression, and gaussian elimination. It's ideal if you need to enter large expressions or have accurate precision. Magic Number Machineis a free, full-featured, graphically laid out, high-precision, scientific calculator for OS X 10.6 or later. The program still works as advertised and I do occasionally release bug fixes, but I will not be adding further features. Developer Note: Magic Number Machine is no longer in active development.
