dc is the Unix standard desktop calculator. AFAIK, there are different implementations (like Solaris or GNU for instance).
What is the exact difference between these implementations and what is the minimal subset of operations you can be sure a dc implementation has?
As far as I could find, at least FreeBSD used to use the GNU-Implementation as well,1 but doesn’t do so anymore. Solaris seems to have a different Implementation.2 From my first read, I mentiones these things:

!=,!>and!<. This is important, because it changes the way shell commands are evaluated. In GNU dc, the sequence!>...is applying the comparison, but in Solaris this would execute the rest of the line as a shell command.Solaris lacks support of
#comments.In Solaris,
