/**
 * Create the possible ranges in a linear distribution from `min` to `max` with

 * This algorithm calculates `bucket_count` number of buckets of equal sizes between `min` and `max`.
 *
 * Bucket limits are the minimal bucket value.
 * That means values in a bucket `i` are `bucket[i] <= value < bucket[i+1]`.
 * It will always contain an underflow bucket (`< 1`).

 * @param min The minimum number in the distribution.
