In particular it seems to me this is poor:
postgres=# select 1::numeric/10;
?column?
------------------------
0.10000000000000000000
(1 row)
In an ideal world it seems to me that if you're dividing by a number with only
factors of 2 and 5 you should only gain as many digits as necessary to
represent the result exactly.
At the very least if you're dividing by a power of ten we should just move the
decimal place and keep the same overall precision.
