39 The SIZE argument is an integer and optional unit (example: 10K is 10*1024).
40 Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).
42 SIZE may also be prefixed by one of the following modifying characters:
43 \&'+' extend by, '\-' reduce by, '<' at most, '>' at least,
44 \&'/' round down to multiple of, '%' round up to multiple of.
