Bitwise operations are mathematical operations done on numbers that can be seen when comparing the binary values of the number. Binary values are another way of writing a number, using a base 2 system. Numbers can be converted from decimal (the normal counting system) to binary using [[$base]].

==The Principal==
When considering bitwise operations, it helps to compare two binary values of numbers. In many of the examples given for the bitwise identifiers in this wiki, the numbers used are 5 and 6. To get the binary values of these numbers, we use base.

$base(5,10,2) = 101
$base(6,10,2) = 110

Each digit above is a bit, therefore $base returns 3 bits for each number. The smallest unit of storage for a computer system is a single byte, which is comprised of eight bits, therefore we will add five 0s to the beginning of each number in our examples to show that we are dealing with one full byte. Adding 0s to the '''beginning''' of a number has no affect on its value, which is why $base removes them for us.

5 = 00000101
6 = 00000110

Note that mIRC uses DWORD values to store numbers, which on most systems is defined as 4 bytes, or 32 bits. Therefore the maximum number possible is 11111111111111111111111111111111 (32 bits long), which by using $base(11111111111111111111111111111111,2,10) we see translates into 4294967295.
