Dinfio Documentation — Function Reference: band()

Module core → band()

Description

Perform bitwise AND operation for the every bit of the given number x and y

band(x, y, bit_width = 32, unsigned = false)

Parameters

x (number) — A number
y (number) — A number
bit_width (number, optional) — The given number x, y, and the returned value will be cast to bit_width-bit integer. bit_width must be in between 1 and 32. The default value is 32
unsigned (boolean, optional) — If unsigned is true then the sign bit of x, y, and the returned value will be ignored. The default value is false

Return Value

number — Returns the value of bitwise AND operation of x and y

Usage Example

a = band(5, 9)                  ' a = 1 -> Where 00000000000000000000000000000101 AND 00000000000000000000000000001001 is 00000000000000000000000000000001 (1 in signed 32-bit)
b = band(0xff, 0x03, 8, true)   ' b = 3 -> Where 11111111 AND 00000011 is 00000011 (3 in unsigned 8-bit)
