Here's some simple code:
put the thumbPos of scrollbar "Slider1" into fR
put fR into msg
The slider has startvalue 1, endvalue 100, and thumbPos 75 (all
set in the property inspector).
This prints out "75" just as I expected.
But fR doesn't *really* have the value 75, as I found out after
literally hours of debugging :-(
If I change the code to
put the thumbPos of scrollbar "Slider1" into fR
put fR && fr+1 into msg
it prints out
75 75.856855
(i.e. fR really has somewhere close to 74.866855 in it, but
"put"ting it for some reason rounds it 75)
I assumed the value of the thumbPos would be an integer - mostly
because the prop inspector won't let me set any other values,
partly because I just expected it to be, and partly because that's
what it appears to be when you examine the variable by outputting
it (or by looking at it in the debugger).
I can deal with non-integral values - but I'm really worried that a
value which was noticeably different from the integer was printed
out as an integer both in the debugger and by "put ... into msg".
Am I missing something basic here ?
Why should Rev be doing this ?
P.S. the reason this took hours to find was that both the put
statements I added for debugging and later the debugger itself were
giving misleading info - if either of them had said "74.85..." I'd
have seen the problem in 30 seconds (I think).
