How to set number of decimal placet of floating numbers at Post-It Panel ?

I am just starting to use Grasshopper and have a simple question.  I have installed the Grasshopper Builds  from  grasshopper_wip_20081202    and
the latest  6.00049

    While  running  the tutorial on exporting data from a Square root function to Excel I noticed that the  values appearing on the Post-it
Panel have only 3 decimal places, while in older versions they had at
least 6.     In general, the floating number values in the Output of
many components appear with only 3 decimal places.  Even with the
simply  Number -component connected to a Post-it Panel.   I tried
through the Rhino display precision, but it didn't work     Where can
I set the number of decimal places in the  Output  of floating numbers.
