As of CVI2013 data tooltips and variable view do some kind of automatic rounding but based on 15 digits only... This prevents tracking numeric / rounding issues. Unfortunately, no possibility exists to show the full precision of doubles... Phrased more drastically one you cannot use CVI to debug numeric issues...
So I suggest to urgently add
- as a minimum version the possibility to show true numbers, not rounded numbers, allowing true debugging
- as a more general version the possibility to adjust the precision of displayed numeric values
