Subject: [PATCH] [project @ 2000-06-12 19:57:40 by panne] Print only the first
 6 characters of the result's decimal representation, this "solves" the
 problem that without optimization 0.46920002 was printed and 0.4692 with -O.
 Perhaps this could be turned into a test for constant folding, but this was
 probably not the test writer's intention.
