--- Comment #1 from Eike Rathke <erack@redhat.com> ---
While generally all floating point numbers that are not exactly representable
in an IEEE 754 double lose precision, this specific case of filling a series of
numbers could be improved by using multiplication instead of incrementing
(adding delta) values.

Actually this shouldn't be too hard to solve, I'm creating an EasyHack of this.
Code pointer is sc/source/core/data/table4.cxx ScTable::Fill() and subroutines.
