very strange behavior of if function resulting in wrong result which might be
a bug.
try it out at your own, and try other values just remember the same
difference.

a1=300 b1=303,6 c1=b1-a1 d1=3,6 e1=if(c1<=d1;"OK";"NOT OK")

the result of e1 should be "OK" but its "NOT OK"

a1=200 b1=203,6 c1=b1-a1 d1=3,6 e1=if(c1<=d1;"OK;"NOT OK")

the result of e1 is "OK"

What the hell is going on ? It does not help to format the cell's.
Have i found a bug, and if it is i will call it a MAJOR BUG which could be
the reson of world economic crisis ;o)
