# CUME_DIST¶

The CUME_DIST function returns the cumulative distribution for each of your partitioned rows between the range of 1/n (with n being the total number of rows), and 1. For example, in a table with ten rows, the cumulative distance for the first row is 0.1 and the second is 0.2, etc. The cumulative distance of the final row is always 1.
