Hi Ryan,
at least my shell is giving a clear error message:

[: 1.2: integer expression expected

and the "man test" command clearly talks about integers being expected. hope this helps,  

Kind regards,
Lex.

Subject: OT:korn shell and arithmetic

I don't know any unix listservs... so I hope this is ok.

I am trying to do the following:

if [ 1.2 -gt 1.0 ]; then

   echo yes
else echo no
fi

It alwys comes out no? Anyway to get around this?

Also when I do:

expr 0 + 0, I get a $? of 1, which kills my error handling. any idea why?
