Functions
band
Definition:
bit.band(w1,w2,...)
Description:
returns the bitwise and of the w's
Example:
print (bit.band (15, 3)) --> 3
bor
Definition:
bitlib.bor(w1,w2,...)
Description:
returns the bitwise or of the w's
Example:
print (bitlib.bor (13, 17)) --> 29
bnot
Definition:
bitlib.bnot(a)
Description:
returns the one's complement of a
Example:
print(bitlib.bnot(10)) --> 4294967285
bxor
Definition:
bitlib.bxor(w1,...)
Description:
returns the bitwise exclusive or of the w's
Example:
print (bitlib.xor (15, 1)) --> 14
rshift
Definition:
bitlib.shift(a,b)
Description:
returns a shifted logically right b places
Example:
print (bitlib.rshift (-1024, 6)) --> 67108848
arshift
Definition:
bitlib.arshift(a,b)
Description:
returns a shifted logically right b places
Example:
print (bitlib.arshift (-1024, 6)) --> -16
lshift
Definition:
bitlib.lshift(a,b)
Description:
returns a shifted logically left b places
Example:
print (bitlib.lshift (-1024, 6)) --> 4294901760
