| Util | Xliff: your second line was missing a final double-quote after `scriptinglanguage`. This does not address your real problem with 0x228a not working; looking at that now. | 00:05 | |

| Util | Of U+2282..U+228B (⊂ ⊃ ⊄ ⊅ ⊆ ⊇ ⊈ ⊉ ⊊ ⊋), the last two (8A,8B) do not appear in the Rakudo source code. | 00:51 | |
| I don't know if that is intentional, or just Not Yet Implemented. | |||
| FYI: used info from www.compart.com/en/unicode/block/U+2200 | |||

| Util | Xliff: To implement, in github.com/rakudo/rakudo/tree/main/src , | 01:16 | |
| most of the code could be cloned-and-hacked in core.c/set_subset.pm6 and core.c/set_proper_subset.pm6, | |||
| with trivial entries also in core.c/OperatorProperties.pm6, core.c/precedence.pm6, Perl6/Grammar.nqp, Raku/Grammar.nqp, Raku/ast/operator-properties.rakumod . | |||
| I don't know if that would actually be in `core.e` instead of `core.c`. | |||
| But, I would suggest filing the issue first, just in case it is intentionally un-implemented. | |||

| camelia | 2023-07-07T00:01:01Z | ||
| Util | Xliff: You must provide a year, or a date, to construct a DateTime. My guess is that there is no clear "correct" default, between year-of-todays-date and year zero. | 02:51 | |
| In docs.raku.org/type/DateTime#method_new , this restriction is detailed via `:$year!` and `:$date!` in the first and second `multi`s. The `bang` forces a (normally optional) named argument to be required. | 02:53 | ||
|
03:03
MasterDuke left
|
|||
| Xliff | Util: That's fine. It is then the error message that is LTA. | 03:05 | |
| Because you CAN call DateTime.new with minute and second named arguments. | 03:06 | ||
| A check with another die if year is not specified would go a long way to cutting down on programmer WTF moments. | 03:07 | ||
| Util | Hmmm. I agree. The message is LTA. However, fixing it should be generalized into everything that has that kind of `multi` constructor (IMO), and the general solution is not obvious to me. | 03:11 | |
| Definitely worth an issue. | |||

| Util | Xliff: relevant to the U+00228A,B issue : math.stackexchange.com/questions/1...eqq-symbol | 04:50 | |
| teatwo | lol, The name of the Unicode codepoint is purely descriptive of the symbol: It is a “subset of” symbol (⊂) above a “not equal” symbol (≠); hence “subset of above not equal”. | 04:51 | |

| xinming_ | Hi, Is there a good way to implement customized rouding logic? Let's say, with 3 digits xyz , with lowest digit z, we round as normal, 9 -> 10, but with y, we round as octal, so 7 -> 10, with x, we round with 4 base, which is 3 -> 10. | 07:34 | |
| I don't mean the actual impelmentation, Some ideas to impelment this will be ok, now, what idea I have is write a class for this. But I fill it might be a bit over kill. | 07:35 | ||
| and I also want to do something like .. operator for this. | 07:36 | ||
|
07:46

|
|||
| nemokosch | Well, if x, y and z are digits of the very same number then I wouldn't call what you described "rounding" in any sense lol | 07:48 | |
|

jpn joined
|
|||
| xinming_ | nemokosch, Yea, sorry for my poor English, What I mean is carry-over. :-) | 07:49 | |
| I used rounding too much in recent days, Which caused me typing rounding. | 07:50 | ||
| nemokosch | Damn, I thought round wouldn't be tied to a base at least... | 08:00 | |
| xinming_ | I know we can have :3<121> kind of things for this, just curious what is the best way to mix different bases | 08:04 | |
| lizmat | . | 08:06 | |
| tellable6 | hey lizmat, you have a message: gist.github.com/a2222449b0759a056b...2c42673d0a | ||
| xinming_ | hmm, the :60<121> is not working. :-( | ||

| xinming_ | I think I'll try to implement something like DateTime | 08:09 | |
| lizmat | xinming_ maybe something like docs.raku.org/routine/polymod could be of use ? | 08:11 | |
