This library allow to specify the internal base of the arbitrary
precision numbers( default is decimal), as well as allows
specification of the precision of floating point values. Each
floating point number precision can be read with .precision().
Also supports specification of rounding modes
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 instanc
https://github.com/acmeism/RosettaCodeData/blob/master/Task/Arithmetic-Rational/D/arithmetic-rational.d
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

Maybe this?

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

I really dont understand what your trying to achieve here.

I am looking for not only free solutions.

Sorry, you still did not state your problem (or what you are
trying to achieve) clearly.
Writing down a clear problem description is likely to get you
halfway to the solution
I want to understand the correct architecture of the class.
Thanks. Do I need to use rational fractions for the Currencies
class?

How about a loop like
import std.stdio;
void main(){
w
without to!string

As I see it, there is no constructor in your class with a double
argument.
What do I need to learn?
module axfinance.api.currencies;
import std.array, std.stdio, std.system, std.bigint, std.conv;
