there are bugs in microsoft exel 2007 for calculation of:
154,2 x 1700 = 262.140 if the result we divide by 4 equal to 100.000 and
then if we multiply again with 4 it's back to 262.140
and also if the result (262.140) we divide by 2 and than multiply again with
2 the result is 100.000
or:
154,2 x 1700 = 262.140 / 4 = 100.000 x 4 = 262.140 /2 = 131.070 / 2 = 100.000

any comment? or do i have to use previous microsoft exel to avoid this bug?


No, you just need to update to SP1.

Probably you have not updated to SP1 This problem was reported, and fixed by
Microsoft, some time ago. It is a problem with the display engine within
Excel, supposedly.
