interesting, and expected as the BCD calculation.  however, the round function 
should be able to handle that correctly, dealing with the number in a string 
fashion as opposed a mathematical one, to display the requested decimal places. 
 slower, to be sure, but hella accurate.

that's what the bug was about.  i understand the issues with BCD.  i don't 
understand how a function to display a number can get the display so wrong, 
even when the BCD number itself "fails" to the 15th place.  round to 2 places, 
you should still display 14.78, not 14.7799999999999999x

just my take.  thanks for getting back to me.
