Maybe I need good examples on C++, for this class, because a lot of examples on C++.

I am looking for not only free solutions.

I really dont understand what your trying to achieve here.

Maybe you can articulate it in one post what this class is trying to achieve?

Maybe this?
https://github.com/andersonpd/decimal/blob/master/decimal/bigfloat.d

The main thing is not to lose currency in calculations that use arithmetic.

Also
http://code.dlang.org/packages/eris

The next version
https://bpaste.net/show/9468f24d9df0

With "eris" lib some problems, the first error:
.../.dub/packages/eris-0.0.1/eris/integer/digits.d(241): Error: cannot implicitly convert expression (digits.length) of type ulong to int

What can I import to use rational numbers?
I found it
https://github.com/dsimcha/Rational/blob/master/rational.d
https://github.com/d-gamedev-team/gfm/blob/master/math/gfm/math/rational.d
but I do not understand what the story ended with rational numbers in D.

https://github.com/acmeism/RosettaCodeData/blob/master/Task/Arithmetic-Rational/D/arithmetic-rational.d

The next version https://bpaste.net/show/dc3c5f10f2ca
I use https://github.com/dsimcha/Rational/blob/master/rational.d
I want to do it:
auto c = new Currencies!Rational.rational.Rational!(BigInt);
where Rational.rational.Rational it is std.rational.Rational
I get the error:
Error: template instance Currencies!(Rational) does not match template declaration Currencies(T)
