FAQ
What bases are supported?
Binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16) — the four most commonly used in computing and mathematics.
Does it handle very large numbers?
It handles numbers up to a very high range reliably, but extremely large values may lose precision — for typical programming and homework use it's more than enough.
What about base64 or other encodings?
This tool covers the four numeric bases used in math and computing — binary, octal, decimal and hexadecimal. Base64 is a different kind of encoding, used to represent binary data as text, not a pure numeral system.
