I set all 8 bits to 1 because I want it to be really true.

[–] laranis@lemmy.zip 94 points 3 weeks ago* (last edited 3 weeks ago) (6 children)

01111111 = true

11111111 = negative true = false

100001111 = maybe not

[–] caseyweederman@lemmy.ca 3 points 3 weeks ago

0011 1111 = could you repeat the question

Schrödingers Boolean

[–] Venator@lemmy.nz 1 points 2 weeks ago

Is this quantum computing? 😜

[–] VonReposti@feddit.dk 34 points 3 weeks ago (4 children)

What if it's an unsigned boolean?

[–] ivanovsky@lemm.ee 25 points 3 weeks ago

Cthulhu shows up.

[–] laranis@lemmy.zip 3 points 3 weeks ago

Common misconception... Unsigned booleans (ubool) are always 16-bits.

[–] ricecake@sh.itjust.works 12 points 3 weeks ago

Could also store our bools as floats.

00111111100000000000000000000000 is true and 10111111100000000000000000000000 is negative true.

Has the fun twist that true & false is true and true | false is false .

Why do alternative facts always gotta show up uninvited to the party? 🥳

[–] pocker_machine@lemmy.world 4 points 3 weeks ago (1 children)

So all this time true was actually false and false was actually true ?

[–] laranis@lemmy.zip 3 points 3 weeks ago (1 children)

Depends on if you are on a big endian or little endian architecture.

[–] pocker_machine@lemmy.world 6 points 3 weeks ago

Come on man, I’m not gonna talk about my endian publicly

[–] Jankatarch@lemmy.world 2 points 2 weeks ago

negative true = negative non-zero = non-zero = true.

[–] OpenStars@piefed.social 15 points 3 weeks ago (1 children)

TIL, 255 is the new 1.

Aka -1 >> 1 : TRUE

[–] ricecake@sh.itjust.works 8 points 3 weeks ago

But only if you really mean it. If not, it's a syntax error and the compiler will know.

[–] p_consti@lemmy.world 12 points 3 weeks ago

I was programming in assembly for ARM (some cortex chip) and I kid you not the C program we were integrating with required 255, with just 1 it read it as false

[–] palordrolap@fedia.io 10 points 3 weeks ago

You jest, but on some older computers, all ones was the official truth value. Other values may also have been true in certain contexts, but that was the guaranteed one.
