Eike Rathke commented on OFFICE-1874:
-------------------------------------

Gnumeric, Excel and OOo for ROUNDUP round away from 0:

=ROUNDUP(9.4567;3)    => 9.457
=ROUNDUP(9.4567;-3)   => 1000
=ROUNDUP(-9.4567;3)   => -9.457
=ROUNDUP(-9.4567;-3)  => -1000

For ROUNDDOWN round towards 0:

=ROUNDDOWN(9.4567;3)    => 9.456
=ROUNDDOWN(9.4567;-3)   => 0
=ROUNDDOWN(-9.4567;3)   => -9.456
=ROUNDDOWN(-9.4567;-3)  => 0

> According to the description 
> If Digits is positive, round to the specified number of decimal places. If Digits is negative, round to the left of the decimal point by -Digits places.
> So 
> =ROUNDUP(1.45673; -2)
> should round to he left of the decimal point and yield 100.
> Similarly
> =ROUNDUP(9;1)
> should be 9 but this seems to be inconsistent with:
> The number returned is the smallest number that is not less than X and is a multiple of 10^Digits.
> Tha sentence should probably be:
> The number returned is the smallest number that is not less than X and is a multiple of 10^-Digits.
