--- Comment #8 from NOYB <junkyardma...@frontier.com> ---
You are talking about internal rounding of calculations.  This issue is about
the ROUNDDOWN function that is applied to a value per the formula given by the
user.  If the user want's it rounded down to 2 digits then 0.93 is the correct
answer/result for a value of 0.9399999999999995.  If the user want's it round
up or to nearest 2 digits then 0.94 is the correct answer/result.  The rounding
functions need to work correctly.  Thus producing and exact result of the
respective rounding function.

Which of these do you reject as not being correct?
Round Up: Increment nth digit.  Truncate >nth digit.
Round Down: Truncate >nth digit.
Round Nearest: If nth+1 digit is 5 to 9, increment nth digit.  Truncate >nth
digit.

The point re: digits of precision is that whatever the underlying precision is,
whether it be 6, 10, 15, 17, 19, etc. digits, the rounding functions should be
accurate.  The ROUNDDOWN function for certain is not.

Function Wizard
ROUNDDOWN( Number, Count )
Rounds a number down to a predefined accuracy.

The ROUNDDOWN function does not reliably do what it claims.  It is flawed. 
Period.
