[postgis-users] Error checking trunk version

[Nicklas Avén]

The difference is 1 extra digit in the expected result compared to
Andreas result. I get the same result as Andrea on PostGISonline which
is 32 bit Ubuntu. The result in "expected" I had from a 64 bit ubuntu
box.

The isolated number that differs shows in

SELECT 	ST_Y(ST_Endpoint(ST_3DShortestline(a,b)))
FROM (SELECT 'POINT(1 1 1)'::geometry as a, 'LINESTRING(5 2 6, -3 -2
4)'::geometry as b) as foo;

-0.19047619047619  (32bit ubuntu)
-0.190476190476191 (64bit ubuntu)

Is this an expected difference between 64 and 32 bit that the sign eats
one digit from 32 bit but not from 64 bit?
