I am trying to define a command to typeset annuity symbols. My attempt
for an ordinary annuity looks like this:
\newcommand{\ordan}[2]{\ensuremath{ a_{\overline{#1\,}\!| #2}}}
In the symbol, the right end of the overline on argument #1 should just
meet the top of the | before argument #2, no matter the height of the
arguments. In
\ordan{100i}{j}
the overbar and the | do not touch, but in
\ordan{\infty}{j}
they overlap. Is there a way to ensure that the overbar and the | meet
at a right angle (as in \urcorner)?
Thanks.
