[geos-devel] Ticket #202 (double hash)

[Ben Harper]

Apologies for sending this to the entire list, but I couldn't figure out how to comment on the ticket alone.
I created an OSGeo user account, and logged in to trac, but still no GUI available.

Anyway, concerning an I32 hash on a double, I think the easiest naive solution
that does not have terrible performance concerns is:

unsigned int HashDouble( double d )
{
 unsigned int* i = (unsigned int*) &d;
 return i[0] ^ i[1];
}
