I am doing the exponent of a number and I need the result to come out in a specific format, however I do not know how to do, follow the code:
double num1 = 290287121823;
double num2 = 538783;
double resultado = Math.Pow(num1, 2) + num2;
My code is bringing 8.42666130962812E+22 but what I need is 84266613096281243382112. How do I do this? I tried formats with .ToString() and force conversion to BigInteger of System.Numerics but it didn’t work out.

The solution really is to use the BigInteger. I used it and it worked, but I did the whole process with it. If the data source was the double, immediately convert each part before performing operations. I didn’t even need formatting.
Behold working in the ideone. And in the .NET Fiddle. Also put on the Github for future reference. With formatting options, although this is not the problem.

Hello bigow, I did a test but it’s like he just added the zeros at the end and missed something in that conversion. Biginteger had generated something similar to me, too, but I haven’t got the right point yet. When the number is smaller than Int64 works well but when it extrapolates and I have to use Double ai something gets lost.

I will test other possibilities by the link you sent. vlw

Opa, then I will test the previous section already doing with Biginteger, was using it only at the end after the calculation. Return now

It worked mustache!! You’re the man! The problem is also that I did not consider using Biginteger.Pow ai was using Biginteger only after the result of Math.Pow, I saw your code there and solved the problem.Thanks
