Numeric modulo operator is incorrect.

Dear sir,

I build PostgreSQL 7.0.3 with jumbo-20010318.patch.gz on Vine Linux2.1.5.

Following result are incorrect. Am I under an illusion?

test=# select '34666624082'::numeric % '34666671'::numeric; ?column?
----------  -46918
(1 row)

test=# select '34666624082'::numeric - '34666671'::numeric* trunc('34666624082'::numeric /
'34666671'::numeric);?column? 
----------34619753
(1 row)
