About the OR Calculator

The OR calculator performs a bitwise OR operation on a list of numbers. The OR operation compares each bit of two numbers and returns a `1` if either of the bits is `1`, otherwise it returns `0`. This tool extends that logic by ORing the first two numbers, then ORing the result with the third number, and so on down the list.

Bitwise OR is commonly used for "setting" bits. For example, if you have a set of flags represented by bits in a number, you can use OR to turn specific flags "on" without affecting the others. This calculator simplifies performing these operations on multiple numbers at once.
