Hi, I've noticed something strange with hslider and vslider. I you give them a large range, the inputs and outputs aren't always equal or at least they are out by a factor greater than 1. For example with the range 0 - 55000, if you connect a number object to hslider's input and enter 6034, the output reads 6032.68.
Couldn't find this reported elsewhere - though perhaps i didn't search hard enough. This result is on linux.
Cheers, i
I think that's because it normalizes the values based on the pixel granularity of the slider. That's just a guess.

Indeed, that is the most likely reason. If you have ability/willpower to try pd-l2ork version of hslider/vslider, this problem is solved in that any values that pass through the slider set to linearly scale between specific values remain unaltered (apart from outer edges of the slider). However, any values that result from moving the slider will be adjusted based on the slider's position in respect to the overall slider.

Thanks Ico, sounds good - will have a look. Nice if your work on this could be applied to standard Pd. Cheers, Iain

Nice fix. I don't see it listed in your change log.
Is it simple enough to make a patch for the sourceforge tracker?

The old changelog is only up to the end of the last year (or thereabouts). All the latest changes are a part of the git now and I do believe that there is a mention of the aforesaid fix in there.

I reported this a loooooooooooooong time ago, in 2006: http://sourceforge.net/tracker/?func=detail&aid=1556206&group_id=557...
It happens, if the slider's range is not divisible by its pixel size. A 100px slider 0...100 is fine, a 100px slider 0 ... 127 is not.
