问题 (I am only an indirect user of the GMP-library primarily through swi-prolog and yap. But I am very much interested in fixing this problem.) When performing exponentiations with ridiculously large values, the host-systems or GMP are no longer able to handle the overflows appropriately. I have talked to the developers of above systems, but they do not see an easy fix for this. Is this problem known to other GMP systems/users? How do you handle such overflows? As a sanity check first test the

问题 Currently, I am using signed values, -2^63 to 2^63-1. Now I need the same range (2 * 2^64), but with positive values only. I found the java documentations mentioning unsigned long, which suits this use. I tried to declare 2^64 to a Long wrapper object, but it still loses the data, in other words, it only captures till the Long.MAX_VALUE , so I am clearly missing something. Is BigInteger the signed long that Java supports? Is there a definition or pointer as to how to declare and use it? 回答1:

问题 I have the following code that creates a very big number ( BigInteger ) which is converted then into a string . // It's a console application. BigInteger bi = 2; for (int i = 0; i < 1234; i++) { bi *= 2; } string myBigIntegerNumber = bi.ToString(); Console.WriteLine(myBigIntegerNumber); I know that for converting to int we can use Convert.ToInt32 and converting to long we use Convert.ToInt64 , but what's about converting to BigInteger ? How can I convert a string (that represents a very very
