Does C ++ have an analogue of java.math.BigInteger?
- Is it a 64-bit integer or for arbitrarily large numbers? - Vladimir Martyanov
- already been. 1 , 2 . - KoVadim
- @KoVadim, BigInteger implementations are also different. For example, the implementation of BigInteger from .NET and the implementation of java.math.BigInteger are different. - Alexis
- Different languages, different implementation. But if the implementation considers that 2 + 2 = 7, then what is the difference, what language / platform / implementation. - KoVadim
- @KoVadim, en.stackoverflow.com/questions/414022/… Productivity is very important in my case. - Alexis

In the standard C ++ library at the moment - no.
boost::multiprecision contains corresponding counterparts. There is both an arithmetic of extended fixed width and dynamic ("infinite") width. There is both a C ++ shell for GMP (the latter must be set separately), and its own independent implementation.

The standard language is not provided. Use one of the available libraries - like GMP

- How, by the way, is she currently supporting Visual Studio? - Vladimir Martyanov
- Although the link can find the answer to the question, it is better to point out the most important thing here, and give the link as a source. If the page to which the link leads will be changed, the response link may become invalid. - From the queue of checks - Kirill Stoianov
- @KirillStoianov read the question and answer; removal is not required here. - Denis

- You have added an example link to a .NET implementation. The labels also indicate pure C ++, not CLI. - Alexis
