# The and (num1, num2) function

This function returns the result of a bitwise AND operation on arguments. There must be at least two arguments. Its syntax is as follows:

`and(num1, num2 [, …])`

In the and operation, for the output to be 1, both the bits that are given as input should be 1 and not 0. The following truth table summarizes how the and operation works when processing two bits:

0 and 0 = 0

0 and 1 = 0

1 and 0 = 0

1 and 1 = 1

The following shows how the and operation works when processing the decimal 5, and 6 illustrates the working of and() function:

5 = 101

6 = 110

5 and 6 = 100 which is decimal 4

The following example shows how the and(num1, num2) functions work:

`\$ vi and.awkBEGIN    {    num1 = 5    num2 = 6    result = and(num1,num2) printf ...`
