7232400 @antirez new units for bytes specification
authored
3 # Note on units: when memory size is needed, it is possible to specifiy
4 # it in the usual form of 1k 5GB 4M and so forth:
5 #
6 # 1k => 1000 bytes
7 # 1kb => 1024 bytes
8 # 1m => 1000000 bytes
9 # 1mb => 1024*1024 bytes
10 # 1g => 1000000000 bytes
11 # 1gb => 1024*1024*1024 bytes
12 #
13 # units are case insensitive so 1GB 1Gb 1gB are all the same.
