Talk:LlRound

In all seriousness, how does a "pretty table", which doubled the page width, https://wiki.secondlife.com/w/index.php?title=LlRound&diff=next&oldid=1187121 fit in with the edit of https://wiki.secondlife.com/w/index.php?title=LlJsonSetValue&diff=prev&oldid=1181771 made for "...better readability on mobile screens..."???

Rounding direction

I can see in retrospect of course that there's no problem in accurately holding -4.5 or -5 in a float. But as for rounding towards positive infinity, is the lslWiki page wrong too? http://lslwiki.net/lslwiki/wakka.php?wakka=llRound Omei Qunhua 13:26, 14 June 2014 (PDT)

Check what LSO does, this may be a difference between LSO and Mono that was never caught... or nobody noticed that llRound is not cmath roundf -- Strife ^{(talk|contribs)} 18:54, 14 June 2014 (PDT)

Just checked ... LSO behaves the same as Mono. And the Mozilla Java Script page says math.round behaves like LSL. http://tinyurl.com/phsk5zy Omei Qunhua 00:22, 15 June 2014 (PDT)

I checked what LSLEditor does and it does the same as Mono. -- Strife ^{(talk|contribs)} 12:13, 15 June 2014 (PDT)

Not for me .

I have 3 different comportements if i am on Second Life , on OpenSim , on LSL Editor

<lsl>

default {

   touch_start(integer total_number)
   {
       llOwnerSay((string)(llRound(-23.5)));
       llOwnerSay((string)(llRound(-22.5)));
       llOwnerSay((string)(llRound(22.5)));
       llOwnerSay((string)(llRound(23.5)));    
   }

} // see explanations here : http://en.wikipedia.org/wiki/Rounding

   // SL : (  round half up ( round half towards positive infinity))

   //[02:42] Object: -23
   //[02:42] Object: -22
   //[02:42] Object: 23
   //[02:42] Object: 24

   // Opensim on Windows (  round half away from zero (round half towards infinity))

// [02:45] Primitive: -24 // [02:45] Primitive: -23 // [02:45] Primitive: 23 // [02:45] Primitive: 24

// LSLEditor on Windows ( Round half to even ( IEEE754, the default mode )) //new: -24 //new: -22 //new: 22 //new: 24 </lsl>

I should test on LSLForge , but i have the strange intuition i will get a 4th different method of rounding

I was lazy and only tested -4.5 -> -4 I didn't remember the even rounding mode. -- Strife ^{(talk|contribs)} 09:18, 16 June 2014 (PDT)
