Conditional Expressions
Formulas can include conditional expressions using the function
IF.
For example,
the
solver accepts the formula:
BONUS=
IF
(SALES
>
3000:
.
02xSALES:
.01
x
SALES)
The two colons inside
the
parentheses
stand
for
NTHEN"
and
NOR
ELSE." According to this formula,
if
SALES are greater
than
3000,
then
the
BONUS equals .02 x SALES; otherwise, BONUS equals .
01
x SALES.
In general, the syntax of
the
IF
function
is:
IF(conditional
expression
:
algebraic
expression
:
algebraic
expression)
The logical
and
relational operators
that
can be
used
in
conditional
expressions are described in table 9-4.
