The rshift (val, count) function

This function returns the value of val, shifted to the right side by the count number of bits specified in the argument. 0s are shifted in from the left side. For example, let us right shift the decimal 5 once time to show how the rshift() function works:

5 = 101

rshift once = 010 which is decimal 2

The following example shows how the rshift() functions work:

$ vi rshift.awkBEGIN    {    num1 = 5    count =1     result = rshift(num1,count)    printf "rshift(%d,%d) = %d\n", num1, count, result}$ awk -f rshift.awk

The output of the execution of the previous code is as follows:

rshift(5,1) = 2
