"VRF" HPVee 4.0 numbers

Question asked by VRFuser on Nov 7, 1997

I also have recently needed to chop decimal positions from displays.  Here is
what I have found.  If you are using a formula ("test data = "+real number) to
combine text and numbers for input to a display the numbers are converted to
text.  Setting the number attributes on the display will not help. 

A couple things you could do:

You can branch your output to two places.  One to the StrFromThru object  for
display and another to your subsequent formulas.


You could do the strFromThru(A, 0, strPosChar(A, ".") + 2)  then pipe the
result to another formula that has the input pin set for real.  This will
convert the text back to real.

Hope this helps,
