Hi,
First of all, thanks to Sebastian & Dimitris.
I think I've got it sussed out now:
Normal[f[x]+O[x,a]/.x->a]
is equivalent to
Limit[f[x],x->a, Direction -> -1].
If x=a is not a singularity of f[x], then
Normal[f[x]+O[x,a]]
will do.
I reckon there's no Normal equivalent for
Limit[f[x],x->a, Direction -> +1]
for "poles" of odd order.
Best Regards.
Ajit.
