Need Help Understanding - IComparer Code

Hi,

I have the following function in a program that I am modifying. I know that its sorting a collection of Card classes by the Rank property.

But I don't understand the code, why are they multiplying the rank value by 100?

Code:

---

private class RankComparer : IComparer<Card> {
    public int Compare(Card x, Card y) {
        return (100 * (int)x.Rank + (int)x.Suit).CompareTo(100 * (int)y.Rank + (int)y.Suit);
    }
}

It shifts the value and condenses two values into just one. It is not neccessary, you can compare ranks and suites separatelly.
