[postgis-devel] BBOX caches: float or double ?

[Sandro Santilli]

There seems to be some confusion about the BBOX cache format.
The liblwgeom/g_serialized.txt seems to suggest that BBOX caches
are using doubles, but code in liblwgeom/g_serialized.c use
floats. Who's right and who's wrong ?

Code using float:

static size_t gserialized_from_gbox(const GBOX *gbox, uint8_t *buf)
 // rounds to nearest float

gserialized_read_gbox_p
 // reads bbox as floats

Note that gserialized_read_gbox_p is supposed to return a GBOX but
given the confusion returns one based on doubles or on floats 
depending on availability of the cache.

This is the reason for bug #1273, but can't imagine how many other
such bugs are hiding...
