See previous discussions concerning the quality of the builtin geometric
types. Not clear that it's worth worrying about, unless you want to go
in for a wholesale overhaul. My own opinion is that PostGIS will
supersede the need for these types...

Not like that. Perhaps use a fraction of the absolute value of the
one with larger absolute value. As-is it's hard to tell how FLT_EPSILON
is measured.
