Ok.. this started a month or so back. None of the other instances of Visio on my LAN seem to have this issue, and removing an re-installing Visio had no impact.
It seems that EVERYwhere I put in a fractional number, it always ends up displaying rounded up, with any associated units shown as ALL CAPS.
Screenshot says it all.
Behavior is even the same when I enter values in a Shapesheet.
For example, if I enter =guard(0.5in) for a value, I see exactly that in the formula bar... UNTIL I hit enter. Then it displays: =Guard(1INCH) in the shapesheet body AND formula bar. Oddly the underlying correct value seems to be there, and function as expected, but it always displays 'UNIT' vs 'un.' or DEG vs Deg., and always the display value is rounded up to the nearest whole number.
AARRRRRRGH!
