 Description   

Test case gis-precise fails on ppc, ppc64, s390 and s390x platforms (diff attached). Generally some integer values are not print as integers again, but as a very similar real number.

The minimal reproducer can be:

select astext(ST_UNION(GeomFromText('POLYGON((0 0, 50 45, 40 50, 0 0))'), GeomFromText('LINESTRING(-10 -10, 200 200, 199 201, -11 -9)')));

This has the following output on x86_64:

GEOMETRYCOLLECTION(LINESTRING(-10 -10,0 0),LINESTRING(-11 -9,8 10),POLYGON((0 0,40 50,50 45,0 0)),LINESTRING(46.666666666666664 46.666666666666664,200 200,199 201,45.33333333333333 47.33333333333333))

but on other arches:

GEOMETRYCOLLECTION(LINESTRING(-10 -10,0 0),LINESTRING(-11 -9,7.999999999999999 10),POLYGON((0 0,40 50,50 45,0 0)),LINESTRING(46.666666666666664 46.666666666666664,200 200,199 201,45.33333333333333 47.33333333333333))

I don't have the platform to confirm, but the idea is clear.
Assigning to Alexey to decide what can and should be done about it.
I've also left initial priority, as set by the reporter, intact; please adjust if needed.

These are Fedora bug reports:

these tests are currently disabled on Fedora 19, but its still something that is worth fixing
