=IF(C9<F9,"0",C9-F9)

Remove the quotes " " from around the 0.

=IF(C9<F9,0,C9-F9)

Enclosing numbers in quotes makes them TEXT. TEXT will always evaluate to be
greater than ANY number.

"0" 1,000,000,000,000,000,000,000 = TRUE

I am Working with Excel 2003 using the IF operator where the correct result
appears but the value doesn't make sense to me. Using the following:
=IF(C9<F9,"0",C9-F9) where C9 is 600,000 and F9 is the product of
10,000,000*.07 which is 700,000 the result is correctly the number zero
(0).

The trouble is if I attempt to use that cell for additional calculations
the
value (0) is greater than any positive number. What am I missing?
