Can we get the exact *input* and the error?  I cant replicate it here:
select round(100::numeric*100, 2);

So... insert into table (field) values (round(100*2, 1)) inserts 100?
I find that quite hard to believe.  Again some actually sql might help
here as I might just be misunderstanding.

Sounds like a problem with whatever is generating the SQL not a
problem with postgres.
