The du manpage does at least.

Note that it is optional though.  You can use flags to decide what you want
and the default is to not use IEC.  ls -h uses humanize_number but not with
IEC units.  In particular, there are flags to control the scaling and
prefixes used: HN_DIVISOR_1000 and HN_IEC_PREFIXES.  The default is to use
power-of-2 scaling with non-IEC prefixes (so KB == 1024 by default).
Currently nothing in base uses HN_IEC_PREFIXES.

(I see you already reverted the printf, just wanted to point out that the
humanize_number behavior is configurable.)
