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:
bit.bor(w1,w2)
Description:
returns the bitwise or of the w's
Example:
print (bit.bor (13, 17)) --> 29
bnot
Definition:
bit.bnot(a)
Description:
returns the one's complement of a
Example:
print(bit.bnot(10)) --> 4294967285
bxor
Definition:
bit.bxor(w1,...)
Description:
returns the bitwise exclusive or of the w's
Example:
print (bit.xor (15, 1)) --> 14
brshift
Definition:
bit.rshift(a,b)
Description:
returns a shifted logically right b places

Description:
convert a bit table into a number
Example:
blshift
Definition:
bit.lshift(a,b) (HTTPLIB)
Description:
returns a shifted left b places
Example:
print (bit.blshift (4, 6)) --> 256
tobits
Definition:
bit.tobits(n) (HTTPLIB)
Description:
convert n into a bit table(which is a 1/0 sequence), high bits first
Example:
blogic_rshift
Definition:
