I particularly recommend checking out hertz and candela.
> Perhaps you'll get the best idea of what Frink can do if you skip down to the Sample Calculations further on this document.
But I never saw that because it was a normal text link in the second paragraph, and because the table of contents is so long I assumed it was the entire document.
There should be at least one sample calculation higher up, with a link to the others, under its own heading called "What you can use Frink for".
>Frink also has a tendency to over-complicate simple matters and use or invent scientific terminology while expressing various concepts, e.g. "Father and I got along like positrons and antineutrinos!" or "microcalifragilistics".
On desktop, for calculation and unit-conversion, I've completely replaced it with Qalculate, which doesn't have a programming language but does have a symbolic solver built-in, which is surprisingly useful for general calculations: you don't have to rearrange your calculation so the unknown is by itself, you can just write the equation from your textbook and replace the thing you want to know with 'x'.
Frink's "Sample Calculations" segment is an amusing read, in much the same ticklish way as xkcd's "What-if" series.
In short, it is a Turing-complete system. Soulver isn't, and that's a huge difference.
I have a bunch of tools in my toolbelt from working in engineering for many years. I always recommend Frink, SMath Studio, and the J programming language among the many tools. I am a polyglot, and I find Frink's simplified Java easy to use for even creating an input window for applications I find myself using repetitively.
