Thank you all - in case I haven't said it recently, this list is wonderful !

Alex, I just did your example, and I got:

  75  76

That was just dragging out a slider, setting the values as you identified,
and typing in the message box. I tested in 2.5.1 - what version of Rev are
you using? And if you're using 2.6, can you try in 2.5.1 and see if you get
a different result?

I'm on WinXP, still 2.5.1
It was a newly created scrollbar - but I had changed the size so that may have 
altered the rounding. Tried a brand new one just now without altering size, and 
get a value of 75.23...

may I suggest

set the numberformat to "0"
put the thumbPos of scrollbar "Slider1" into fR
put fR && fr+1 into msg


I think we're seeing some kind of dithering when it comes to slider values if the numberformat is not set to represent an integer. The slider has a finite number of gradations possible at 72 dpi for mac and ?? for windows.. and they don't always line up right, hence the odd fraction. This is normal. Just make sure you set the numberformat.

That works well - thanks.
Given that success, I also tried setting the numberformat of the scrollbar itself, to "0", but that didn't work.

Thanks - I'll add the info about numberformat of the scrollbar being ineffective ...
