Quoting find(1):
The + and - prefixes signify greater than and less than, as
usual; i.e., an exact size of n units does not match. Bear in
mind that the size is rounded up to the next unit. Therefore
-size -1M is not equivalent to -size -1048576c. The former only
matches empty files, the latter matches files from 0 to 1,048,575
bytes.
