Thanks for you answer and explanation. Is there a reason why you do
not add \| to get double bars? This is the way it is done in LaTeX
(OK, not really an argument). I'm just curious.

this is because lm has no such characters so they are made from the

in traditional lm this can go unniticed (depends a bit in the exact

i've added double bars so this works:
$\biggl\Vert x^n\biggr\Vert$
$\biggl{||} x^n\biggr{||}$
$\biggl|\biggl| x^n\biggr|\biggr|$
there will be a new beta later today or tomorrow

Ok Hans, with the beta from yesterday the absolute values change size,
but there are some problems still:
1) The absolute value bars are not just "straight lines" when using
\big and friends, but som kind of line that is thicker in the middle.
(zoom i on attached pdf)
2) The horizontal spacing in the \big version seems to be bigger than
for the \bigl/\bigr version (and similar for \Big vs \Bigl/\Bigr). I'd
expect the same spacing (the l and r are just there for the writer to
easily see what is left and what is right).
3) I'd expect that \| gives double bars, like the || one get from
\Vert and not |. This is not so (see the attached file). Moreover, it
is not possible to do \bigl\Vert right now to get a bigger ||.
