Formula references

Formula references

[Michal Kvasnicka]

Hello!

How can I make the formula references be enclosed in brackets?
I mean this:
    bla bla bla \in{equation}[eq:bum] bla bla bla
should give me
    bla bla bla equation (1) bla bla bla

Many thanks for your kind help.

Formula references (once more)

Dear friends!

Excuse me being hard-headed, but I will repeat my question (since I
havn't got
answer and I need it):

How can I make \in macro enclose the formula number in parentheses?
I'd like
    \placeformula[eq:bum] $$ a = b $$
    ...
    \in{equation}[eq:bum]
to produce:

    a = b
    ...
    equation (1)

Can you hint me?

Many thanks and greetings.

M.K.

Page 215 of the beta manual cont-enp.pdf explains how to do that.

Not possible without rewriting things as far as I know the source. You
can always write a:

\def\myin[#1]{(\in[#1])}

or something like that of course.

\definereferenceformat
     [informula]  
     [left=(,right=),text=]

In you paper, use \informula[eq:myeq] will get reference such like (1).
