Do not try to expose too many different ideas. Simplify your message and repeat it over several times with different words.
If it relates to something else (a GiHub repo, etc) don’t spend time getting deep into that, just give a brief reference (“and this can be checked in url blablabla). Summarise. If they are interested in dig deeper, they’ll go to the linked stuff.
The IDE approach (single tool integrating all the operations) and the VIM approach (VIM just to edit a file, other tools in Unix to perform other operations) are different. It’s ok to prefer one or the other. It’s OK to change from one another. It’s fine, really.
Learn what you want and your tools and change them if they don’t suit your flow. Evolve and change your opinion. Enjoy.
John von Neumann, probably.
What language should one use for floating point calculations?
TCL, of course, because EIAS!
In most languages there are libraries to deal with precise numbers. For example, you can use Decimal in Python. https://docs.python.org/3/library/decimal.html
But it may not be as fast or have other inconveniences (for example, defining explicitly the precision)
There are some good examples in the list @HugoDaniel posted in this thread.
Here’s something interesting for JS: http://mikemcl.github.io/decimal.js/
If you want it to work correctly, then probably SPARK, C w/ tooling, or Gappa w/ language of your choosing. If performance isn’t an issue, there’s a pile of languages with arbitrary-precision arithmetic plus libraries for those without it. I’d say that’s the options.
Meanwhile, there’s work in formal methods on Exact-Real Arithmetic that could give us new options later. There was an uptick in it in 2018. I’m keeping an distant eye on it.
The module sh is a fantastic tool for these kind of scripts. https://github.com/amoffat/sh
