A1:
=FACT(9)/FACT(6)/FACT(3) returns 84, as it should

A2:
=COMBIN(9,3) returns 84, as it should

A3:
=A1=A2 returns TRUE

A4:
=A1-A2 returns 0

A5:
=MOD(A4,1) returns 0

A6:
=MOD(A1,1) returns 0

A7:
=MOD(A2,1) returns -1.42109E-14

So the @#$% fudge factor strikes again, or does it? Shouldn't it affect
the evaluated value of cell A2 with the final result for A2 an integer?
This shouldn't be. If cell A4 is zero with no remainder in A5, why
should A7 have a remainder?

Same results in 2003 and 2007.
