modulo negative
Hi.
Please see attached. When you move the incdec, it cycles around 1-8, but if you go into negative numbers, it breaks the cycle. Any suggestions?
Cheers
depends on what you want in minus range.
insert abs at the end and you get
-1 = 1
you can use
expr abs($i1%8)
instead for same effect.
if you want
-1 = 7
then
expr abs($i1%8+8) %8
expr abs($i1%8+8) %8
This is great, except for one thing. When it gets to 8, i get a zero. This is musical bars, so i want the range to be 1 -8.
I could fix it with a [sel 0], but that feels kind of ugly. Any way to fix that within the [expr] object?
Thanks
expr abs($i1%8+8) %8 + 1
[pong 1. 8. @mode wrap] ?
or save this as [110.loopi]
expr ((($i1%$i2) + ($i2)*(($i1%$i2)==0))*($i1>=0)) + ((((($i1%$i2)+$i2) + (-$i2)*((($i1%$i2)+$i2)==0))*($i1<0)))
low end of the range is always 1 (i once made it for the same purpose), high end has to be set as argument for $f2
this will also work, maybe it is a bit shorter and better to control and modify for third parties, compared to the loopi bandworm above.
That last one is perfect. Thanks Roman. Thanks all.
when i think about it, you could also use [substitute 0 #1] instead of the lower expr.
i am amazed how some of my tools shrink in size over the years. :D
haha, brilliant. Eventually all our patches will just have 2 objects and work perfectly :)
actually, that doesn't work. I just get 0
doesn't work for me anyway. Here's a bit more context.
maybe i did something wrong; i quickly tried that in max 8 yesterday and only connected a numberbox ... this does not make sure that substitute actually sends out message type LONG... which i cant tell offhand now. ;)
but the other alternatives are [select 0] [t 16], which is very unsexy, and [if], which consumes even more CPU than an [expr] in int mode.
(in a scheduler context i usually go by that rule that if you need more than 3 objects to avoid a überlong expression, then the chance is higher that expür is more effective.)
Ah, it's fine. The previous solution works perfectly anyway :-)
