There is Money datatype that can be provided by using a third

But that's only for money, what about math?
Why such fundamental as BigDecimal is still not included into
the D language itself?
There is BigInt.
If it is unavoidable to use Floating point, how can I quickly
and simply understand the rules of using float to make the
least error, or should I just find a third party package for
that as well?
There is an article on that, but it is not that straight
forward:

Basically any thing that I find on Google, that include
explaining floating point are badly written and hard to
understand for the outsider lacking ability to understand
advanced concepts.
I recommend that you learn floating point math as this will help
you not only in programming in D, but in any other language.
In any case, if you need super-high precision, you might want to
give decimal [1] a try.
