The following works

Note the backslash before prec in the macro body has to be escaped with another backslash. I inverted the nesting of the macro and conditional here.

Aha :)

Note also that you can't do @macro prec because @prec is already
defined as a control sequence.


The "@tex" and "@end tex" lines have to be on lines by themselves. Any
backslashes in a macro body should be doubled, as well.

Just adding newline to make that happen seems to break the inline format macro. So..

a @precb{} b

Seems to do the trick, just /one/ little issue is that it doesn't seem to allow you to format the whole thing as math in one go, e.g.:

  @math{a @precb{} b}

Makes stuff unhappy.

Is there a way to make that work?

Thanks very much! :)
