Hi,
Thank you for the answer.
Do you know if it's planned ?
Do you know a workaround?
Regards,

That query doesn't work. If the field contains 0\n, that would match (300A)

Is the way in which SQLite handlesNaN and Infinity values as defined

I am not quite sure what you are saying. I am pretty sure that NULL is

So every value of all types matches with it.
I don't understand what matches with means in this context, sorry.

Hi Jay,
However, it is worth remembering that IEEE 754 is really about building
processors, not about end-user interaction. While it is a rigid,
formal specification of a numeric environment, at its heart it is

Hi Simon,
Null is a special marker used in Structured Query Language (SQL) to indicate
that a data value does not exist in the database.
To me, this statement does not apply to NaN, which is a perfectly
fine (albeit unusual) floating point value.
If you compare anything with NULL, you will

Hi Simon,

Well yes, it does, but my entire point is that floating point NaN is
quite different from Unknown.
SQLite sort-of unifies NaN and NULL (although this isn't documented).
However, this is not an SQL choice -- it is an
