Questions
How do I add binary numbers?
Binary addition follows the same rules as decimal but with only two digits: 0+0=0, 0+1=1, 1+0=1, and 1+1=10 (carry the 1). This tool automates the process for you.
What is binary used for?
Binary (base 2) is the fundamental number system used by computers. All data in a computer is stored and processed as sequences of 0s and 1s.
How do I convert binary to decimal manually?
Multiply each bit by its positional power of 2 (starting from 0 on the right) and sum the results. For example, 1011 = 1x8 + 0x4 + 1x2 + 1x1 = 11 in decimal.
What is the largest number I can enter in this binary calculator?
The calculator handles standard JavaScript integers, which means it can work with binary values up to 53 bits (the safe integer limit). For most practical purposes this is more than enough.
Does this binary calculator work offline?
Yes. All arithmetic runs in your browser with no network requests. You can use it without an internet connection after the page loads.
