Click Install to perform a default installation.The Install WolframScript dialog appears.In the Mathematica installer window, double-click the WolframScript.pkg icon to run the WolframScript installer.Mathematica also comes with an optional WolframScript installer.
Next, activate the software to start using it. Mathematica is now installed in your Applications folder.
What this means is that smallish machine precision values might get chopped inside code that is primarily based on exact methods. 2019: OS:-Windows 10-Windows 7 Service Pack 1-Windows Server 2016-Windows Server 2019. (3) Try to get cancellations to be sensible e.g. MacOS: Operation System:macOS Catalina (10.15) / macOS Mojave (10.14) Note:macOS High Sierra (10.13) is no longer supported / On macOS Mojave, version 10.14.6 is recommended.
(2) Avoid "small" residual expressions wherein coefficients are on the order of a machine precision ULP (because these really mess up zero testing and related things that rely on a decision procedure, hence will mess up Series, Limit, Integrate. The things I have tried to optimize for include With machine numbers there is not a chance that all heuristics will meet all needs at all times. With bignums and significance arithmetic these changes generally do alright.
The 500+ functions from Mathematica 1 are still in Mathematica 12but there are now nearly 6,000, as well as a huge range of important new ideas that dramatically extend the vision and scope of the system. These are all based on exact methods that have, of necessity, been adapted (more to the point, coopted) for use in the realm of approximate coefficients. The Mathematica Trajectory Its Come a Long Way in Three Decades. (Full)Simplify has to rely on any number of methods that manipulate rational/trig functions. From simple calculator operations to large-scale programming and interactive-document preparation, Mathematica is the tool of choice at the frontiers of scientific research, in engineering analysis and modeling, in technical education from high school to graduate school, and wherever quantitative methods are used.
I very much doubt this will be "fixed" in any general way, and in fact am not convinced it is "broken" (in any general way). Mathematica 5.2 Professional Version for Macintosh OS.
