The line of code that is equivalent to a/4 given that e maximum integer, min_int is the minimum integer, and w is one less than the word length (e.g., w = 31 for 32-bit integers is:

(4)   ((a<0)?(a+3) : a)>>2

Suppose we take a=4 ,

the result is 4 , 4>>2=1

a/4 = 4/4 =1

Thus, assuming that variables a and b are signed integers and that the machine uses two complement representation; and also assuming that MAX INT is the highest integer and MIN INT is the smallest integer, and that w is one less than the word length for 32 bit integers,

The line of code that matches a/4 = ((a<0)?(a+3) : a)>>2
