Unique Ranks Function

I have a list of data where some of the cell values are the same. I want to rank them uniquely but when I use the RANK function the cell values that are the same are given the equivalent rank. Is there any way of assigning the equivalent values a sequential ranking that is unique?

So in this example rather than producing the rank as this:

100 1
99 2
98 3
98 3
98 3
97 4
96 5
95 6

It would produce it as this:

100 1
99 2
98 3
98 4
98 5
97 6
96 7
95 8
