| Aug 14, 2023 at 20:37 | comment | added | Peter Cordes | Thanks, good update. (Other non-string integer representations not called "binary" I should have used for examples include BCD and Gray code. The existence of stuff like that is another part of why "binary integer" is meaningful when talking about numbers stored in registers or bytes in memory.) | |

Could I suggest a test case of 0000 to result in an empty output?

| Aug 12, 2023 at 19:41 | comment | added | Peter Cordes | (I always find it weird when people talk about "decimal" or "hex" numbers in asm questions on Stack Overflow when they're just talking about source code representations! That's the same kind of sloppyness (or error) I often see in code-golf questions when discussing number representations in terms of golf langs. With assembly language, I've had lots of experience thinking about terminology for discussing ASCII string (in some base) representations of numbers vs. binary integers vs. floating point, vs. various bigint formats vs. esoteric object-representations in some code-golf questions.) | |
| Aug 12, 2023 at 19:39 | comment | added | Peter Cordes | @LevelRiverSt: Yes, that's the point of my comment, too, explaining to the OP why it's not obvious from the question's phrasing that an integer input isn't allowed. Even their reply in a comment replying to yours doesn't close the loophole: an integer is in binary in many languages. But despite that, I think they do intend to disallow integer types so this is a string-to-string conversion (or an array/list of digits). | |

@PeterCordes there are existing answers with arrays of 0 and 1 as well as strings, but as you noted, the point of my comment was to recommend explicitly closing the loophole of calling an integer a binary representation.

In other words, a binary integer in a register is a normal way for a function to accept binary numbers as input, and the most obvious / simple / efficient. If you mean a base 2 string representation of a number, say that. I agree with @LevelRiverSt on this. Your examples are string-like, but that could be assumed to be catering to languages that don't natively have binary integer types. (e.g. Javascript, where numbers are floating-point, not binary integer.) Also, a string of 1-bit digits can be packed into a register (or C unsigned int); that's a good way to store binary!

In some programming languages, such as C, integer types are guaranteed to be binary. For example, uint32_t is guaranteed to be a 32-bit unsigned type with no padding, with the place-value of the bits being 2^0, 2^1, etc. Same for assembly languages for normal binary computers. In such a language, if you choose to take an integer input, the challenge ends up being the same as Output / Convert to unary number (where my answer is just an x86 machine code memset(dst, '1', n).)

| Aug 12, 2023 at 6:24 | comment | added | noodle person | @LevelRiverSt It has to be in binary, that’s kind of the whole point, I guess I thought that was obvious | |

any reasonable input & output format I'm guessing taking the input as an integer is not acceptable, but it would be good to state it explicitly.

| Aug 11, 2023 at 20:05 | comment | added | noodle person | @KevinCruijssen I’m going to say no, since it doesn’t really feel like base-1 at that point. | |

| Aug 11, 2023 at 19:21 | comment | added | Kevin Cruijssen | May the unary output be a mixture of multiple characters, instead of one distinct one (as long as its length is correct of course)? | |
