The Binary Converter accepts an unsigned integer in several source notations and reports binary, decimal, hexadecimal, octal and bit length. The Binary to Hexadecimal Calculator focuses on the binary/hexadecimal pair with a shorter, capped input workflow.
| Feature | Binary Converter | Binary to Hexadecimal |
|---|---|---|
| Source modes | Binary, decimal, hexadecimal, octal, and width-preserving hex → binary | Binary → hex or hex → binary |
| Target controls | Mode-specific selectors for the other bases; width-preserving mode targets binary | Direction selector |
| Input | Text digits for the chosen base; spaces and underscores ignored | Numeric binary field, or 1–4 selected hex digits |
| Stated bounds | BigInt integer arithmetic; available memory and resources still bound input | Binary at most 16 digits; hex 1–4 digits |
| Supporting panel | Four representations plus bit length | Entered binary or hexadecimal digits |
The hub default 101101₂ displays 45 in decimal. Selecting hexadecimal source makes its hexadecimal text field active; selecting a different target changes the primary answer. Its ordinary hex → binary conversion reads 000F as the integer 15 and displays 1111. Its explicit width-preserving hex → binary mode instead displays 0000 0000 0000 1111, retaining four bits for each of the four entered hex digits.
The focused form defaults to binary 1010, giving hexadecimal A. Reverse mode with four selected digits 000F gives 0000000000001111. Both tools therefore have an explicit hex-width workflow. The focused binary field is numeric, so it is not a text-width-preserving input.
Hexadecimal uses 16 digit values, 0–9 and A–F; 16 = 2⁴ explains the four-bit mapping. When binary digits are converted to hexadecimal, groups are anchored at the right and a short leading group is padded on the left. The hub’s display can insert spaces, leaving a shorter first group; Copy uses the ungrouped output digits. For width-preserving 000F, its copied binary output retains all 16 bits without display spaces. The focused tool also copies the digit representation with base subscripts.
Neither form interprets fractions, negative signs or signed machine-word encodings. Integer arithmetic avoids rounding a large whole number through an ordinary floating-point value, but it does not establish unlimited input capacity.
