After applying an AND logic over the original number the result is shifted so the function returns just the extracted bits. WebBITAND returns a decimal number. The result is a bitwise 'AND' of its parameters. The value of each bit position is counted only if both parameter's bits at that position are 1. The values returned from the bit positions progress from right to left as powers of 2. The rightmost bit returns 1 (2^0), the bit to its left returns 2 (2^1), and so on
