redis中的sortedset中的score值的大小，是否会影响占用空间的小大
相同的数据，score使用很长的一个double值(10位以上数字)和一个int16(5位数字)，占用的空间大小是否一样，
使用int16的score是否会更节省空间呢？

Refer to Chapter 8, Section 8.6, p78 of "Redis Design and Implementation": "The member of each element in the ordered set is a string object, and the score of each element is a double-type floating point number. ". In other words, for zset, redis uses a fixed double type to represent numbers, instead of using "up conversion" to store numbers like an integer set.
