@movq@www.uninformativ.de Yup, I’ve also seen the floating point conversion happening with (1 << 63) - 1 yesterday night. But instead of pausing to think about it for a second, somehow all I had in mind was “give me a better representation, ain’t gonna have time for this shit”, so I turned it to hex. Beyond my comprehension what I was thinking there. O_o That’s embarrassing, unbelievable. Well, I blame late o’clock where my brain had already quit on me and went to bed.

Very interesting data point you raise there. The fun part didn’t cross my mind yet or at least I couldn’t pinpoint it. In hindsight it’s totally obvious, though. Past experience also tells me the exact same. Dealing with a problem and researching something myself is a so much more better teacher. The longer I faced up with a topic, the higher the chance to really manifest in long- or at least mid-term memory. If I just get told something, the odds are that it’s completely erased from memory in a matter of days if not hours.

@lyse@lyse.isobeef.org AI result ahead, feel free to ignore.

I “asked” the AI at work the same question out of morbid curiousity. It “said” that SQLite converts that integer to floating point internally on overflows and then, when converting back, the x86 instruction cvttsd2si will turn it into 0x8000000000000000, even if the actual floating point value is outside of that range. So, yes, it allegedly actually saturates, as a side effect of the type conversion.

I couldn’t find anything about that automatic conversion in SQLite’s manual, yet, but an experiment looks like it might be true:

sqlite> select typeof(1 << 63);
╭─────────────────╮
│ typeof(1 << 63) │
╞═════════════════╡
│ integer         │
╰─────────────────╯

sqlite> select typeof((1 << 63) - 1);
╭──────────────────────╮
│ typeof((1 << 63) ... │
╞══════════════════════╡
│ real                 │
╰──────────────────────╯

As for cvttsd2si, this source confirms the handling of 0x8000000000000000 on range errors: https://www.felixcloutier.com/x86/cvttsd2si

The following C program also confirms it (run through gdb to see cvttsd2si in action):

<a href="https://we.loveprivacy.club/search?q=%23include">#include</a> <stdint.h>
<a href="https://we.loveprivacy.club/search?q=%23include">#include</a> <stdio.h>

int
main()
{
    int64_t i;
    double d;

    /* -3000 instead of -1, because `double` can’t represent a
     * difference of -1 at this scale. */
    d = -9223372036854775808.0 - 3000;

    i = d;
    printf("%lf, 0x%lx, %ld\n", d, i, i);

    return 0;
}

(Remark about AI usage: Fine, I got an answer and maybe it’s even correct. But doing this completely ruined it for me. It would have been much more satisfying to figure this out myself. I actually suspected some floating point stuff going on here, but instead of verifying this myself I reached for the unethical tool and denied myself a little bit of fun at the weekend. Won’t do that again.)

@lyse@lyse.isobeef.org

Disclaimer: Can’t guarantee that I’m fully awake and I’m being trained at work not to use my brain anymore, so maybe this is complete bullshit. 😪🧟‍♀️

It says here that SQLite uses signed integers:

https://sqlite.org/datatype3.html

In pure bits, 1 << 63 would be 0x8000000000000000, but as a signed value, it gets interpreted as -9223372036854775808. Subtracting 1 yields -9223372036854775809 – but that doesn’t fit in 64 bits anymore. It’s possible that SQLite doesn’t want to wrap around but instead saturates? Haven’t checked. 🤔

With 62 bits, there is enough room.

With 1 << 64, I have no idea how SQLite wants to handle this, because this should immediately trigger a warning, because it doesn’t fit right away. Maybe it gets truncated to 0?

sqlite> select printf('0x%x', 2 * (1 << 64));

Eehhh, what the hell is going on here!?

SELECT
    printf("0x%x", (1 << 63) - 2),
    printf("0x%x", (1 << 63) - 1),
    printf("0x%x",  1 << 63     ),
    printf("0x%x", (1 << 63) + 1),
    printf("0x%x", (1 << 63) + 2)

SQLite yields:

0x8000000000000000 (instead of 0x7ffffffffffffffe)
0x8000000000000000 (instead of 0x7fffffffffffffff)
0x8000000000000000 (correct)
0x8000000000000001 (correct)
0x8000000000000002 (correct)

Huh!? O_o Am I stupid? What am I missing here? Or is this actually a bug? :-?

With 62 bits, everything is spot on:

0x3ffffffffffffffe
0x3fffffffffffffff
0x4000000000000000
0x4000000000000001
0x4000000000000002

And 64 bits rather unsurprisingly also yield:

0xfffffffffffffffe
0xffffffffffffffff
0x0
0x1
0x2
