Bug in setting setting the height of rectangles

[Jim Hurley]

I have been getting some strange results setting the heights of 
graphic rectangles--programmatically.

For example the following run from the msg box:

put the height of grc 1 & return after results
set the height of grc 1 to (the height of grc 1) + 0.1
put the height of grc 1 after results
put results

Gives:

70
70

As it should. The addition of .1  to the height should have no 
effect. Graphic 1 is a rectangle.

But

put the height of grc 1 & return after results
set the height of grc 1 to (the height of grc 1) - 0.1
put the height of grc 1 after results
put results

Gives:

70
69

Whereas it should give

70
70

Subtracting .0000001 from the height also gives

70
69

(The +.1 and -.1 arise from a variable determined from a calculation.)

Mac OS 9, RR 2.1.2

If anyone can confirm this, I will Bugzilla it.
