Bit from 4-byte - 2MAX - 11.01.2023
Hello,
i need extraxt every single of 32 bit from 4-byte
i try this scrip but something is wrong, because ist always FALSE on eaxh bit
value = event.getvalue()
function getbit(value, nr)
value = bit.rshift(value, nr)
return bit.band(value, 1)==1
end
bit0 = getbit(value,0)
log(bit0)
bit1 = getbit(value,1)
log(bit1)
.
.
.
.
bit32 = getbit(value,32)
log(bit32)

What is the datatype of source object? What do you get when logging the value?
Code:
value = event.getvalue()
log(value)RE: Bit from 4-byte - 2MAX - 11.01.2023

Check the script carefully, might be copy-paste error there. For 67108864 only bit 26 will be true.
Also there's no bit 32, indexing starts from 0, the maximum bit is 31.
