BigInteger division in C#

Question

I am writing a class which needs accurate division of the BigInteger class in C#.

Example:

BigInteger x = BigInteger.Parse(\"10000000000000000000000         


        

Answer 1

In the above example, the numbers are still small enough to be converted to double, so in this case you can say

double result = (double)x / (double)y;

If x and y are too huge for a double but still comparable, maybe this great trick is helpful:

double result = Math.Exp(BigInteger.Log(x) - BigInteger.Log(y));

But in general, when the BigInteger are huge, and their quotient is huge too, this is hard to do without importing a third-party library.
