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.
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
I set all 8 bits to 1 because I want it to be really true.
01111111 = true
11111111 = negative true = false
00001111 = maybe
10101010 = I don’t know
100001111 = maybe not
0011 1111 = could you repeat the question
00000001 00000000 00001111 10101010
Schrödingers Boolean
Is this quantum computing? 😜
What if it’s an unsigned boolean?
Cthulhu shows up.
Common misconception… Unsigned booleans (ubool) are always 16-bits.
Could also store our bools as floats.
00111111100000000000000000000000is true and10111111100000000000000000000000is negative true.Has the fun twist that true & false is true and true | false is false .
negative true = negative non-zero = non-zero = true.
So all this time true was actually false and false was actually true ?
Depends on if you are on a big endian or little endian architecture.
Come on man, I’m not gonna talk about my endian publicly
Why do alternative facts always gotta show up uninvited to the party? 🥳

TIL, 255 is the new 1.
Aka -1 >> 1 : TRUE
