I was attempting a problem on Project Euler - Problem 20.
Since 100! could not be stored as ulong, I was thinking of using hexadecimal. Though I find a lot of example of converting hexa to decomal and vice - versa, I cannot find any info on using it in calculations. I have the code for the problem ready, but the size of the number is huge.
P.S. : I don't want the solution to the problem.
