Replying to [comment:3 sbl]:
> At the end it is also a question wether NaN or Inf is preferable over
NULL in the database...
Well, for rasters, NaN is null (in 6.x, one specific NaN is treated as
null, in 7.x any NaN value is treated as null). Also, code which is
expecting a definite value probably won't handle a NaN correctly because
of their unusual semantics.
Ideally, infinities should be preserved rather than converted to an SQL
NULL. If this is just a matter of fixing the int<->string conversions
(rather than blindly using e.g. sprintf/sscanf "%f"), then it should be
done.
