on the fight. For example,
when you select MATH from the left, the
corresponding
math functions
appear on the fight. If you select ALL from the

on the fight in alphabetical
order.
This section

More detailed
information
is in the Appendix,
beginning
on page

Financial
functions
Financial
functions
provide
formulas
for common
financial
calculations.
For
example,
the FV (Future
Value) function
calculates
the future
value
of a
stream
of regularly
invested
payments.
The arguments
for financial
functions
are either
values
or addresses
of cells
that contain
values.
When
the argument
is the interest
rate, express
it as its
actual
value
(.07 rather than 7 to indicate
7%). Be sure to specify
the same
units
for the term and the interest.
If the interest
is monthly,
the term is also
monthly.
Information
functions
The information
functions
return
information
about
a cell or range
of cells.
For example,
the COUNT
function
counts
the number
of items
in a list.
