| 2024-11-05 19:50:29 +0100 | <tomsmeding> | it refers to C11 |
| 2024-11-05 19:50:25 +0100 | <tomsmeding> | the wikipedia article has a citation, perhaps that helps? |
| 2024-11-05 19:50:14 +0100 | <dolio> | I probably don't know what term to search for. |
| 2024-11-05 19:49:55 +0100 | <tomsmeding> | dolio++ for even trying |
| 2024-11-05 19:49:25 +0100 | <dolio> | I tried to look in my copy of the standard, but it's hard to find stuff in there. |

| 2024-11-05 18:14:50 +0100 | <tomsmeding> | now I'm aware that wikipedia is not a definitive source :) |
| 2024-11-05 18:14:42 +0100 | <tomsmeding> | wikipedia agrees with me (last paragraph of the introduction) https://en.wikipedia.org/wiki/Integer_overflow |

| 2024-11-05 18:13:24 +0100 | <tomsmeding> | and I'm fairly sure that it's actually _defined_ to wrap, not only implementation-defined |
| 2024-11-05 18:13:08 +0100 | <c_wraith> | in all cases it *is* defined! |
| 2024-11-05 18:13:03 +0100 | <tomsmeding> | (certainly not saturating because then the common implementations would be wrong) |
| 2024-11-05 18:12:45 +0100 | <tomsmeding> | for regular old unsigned types, it's wrapping |
| 2024-11-05 18:12:32 +0100 | <c_wraith> | I can't remember if C defines the results as wrapping, saturating, or makes it implementation-defined |
| 2024-11-05 18:11:43 +0100 | <tomsmeding> | so what did you mean with "implementation-defined"? |
| 2024-11-05 18:11:28 +0100 | <tomsmeding> | okay sure |
| 2024-11-05 18:11:23 +0100 | <c_wraith> | yeah |
| 2024-11-05 18:11:18 +0100 | <tomsmeding> | because of wraparound? |
| 2024-11-05 18:11:06 +0100 | <c_wraith> | just that the results are often going to violate assumptions made elsewhere on the program. that has been a recurring source of bugs in programs. arithmetic that would be right with a signed type being wrong with an unsigned type |
| 2024-11-05 18:10:43 +0100 | <tomsmeding> | c_wraith: "no" to "subtract" or "no" to "can't" :D |
| 2024-11-05 18:10:03 +0100 | <tomsmeding> | unsigned integer wraparound is defined in C; does that not extend to size_t? |
| 2024-11-05 18:09:59 +0100 | <c_wraith> | im pretty sure it's not UB, as it's an unsigned type |
