Fundamentals
pow => powerOf => x^y
A simple function I use all the time because I cannot be bothered to remember how to use Math.Pow(). Also, who uses double anyway? Pshh, real men use BigInteger.
using System.Numerics;
public class basic
{
public static BigInteger pow(long down, long up)
{
BigInteger power = 1;
for (long i = 0; i < up; i++)
power *= down;
return power;
}
