NAME
       fmt_human - write a human readable ASCII representation of a long
       integer

SYNTAX
       #include <fmt.h>

       size_t fmt_human(char *dest,unsigned long long source);

DESCRIPTION
       fmt_human writes a human readable ASCII representation of source to
       dest and returns the number of bytes written.  The result resembles the
       file size output of "ls -H"; 1000 becomes "1.0k", 1000000 becomes
       "1.0M" and so on for "G" and "T".

       fmt_human does not append \0.

       If dest equals FMT_LEN (i.e. is zero), fmt_human returns the number of
       bytes it would have written.

       The output of fmt_human can not exceed 11 (assuming unsigned long long
       has 64 bits).
