COS
(N)
Calculates the cosine of N. The value N should be in radians. If N is
expressed in degrees, use COS (N*.O 1745329) to compute the cosine.
COUNT (list)
Returns the count of the number values you list. Multiplan counts cells
only if they contain number values.

Multiplan counts only the values in the cells that it evaluates between two
successive DELTA operations.
DELTA ( )
Returns the maximum absolute value of the changes in values from one
iteration to the next.
#
N/A appears if you choose No at the iteration field
in the Options command.
To avoid problems with order of evaluation, enter the first DELTA
function in the cell immediately above the block of cells for which you
want a local DELTA value. Then, enter the test DELTA formula in the
cell immediately below the block of cells to return a local DELTA value.
The DELTA operation displays the
#
N/A error when ITERCNT ( )
=
I or
when ISNA (lTERCNT ( )) returns TRUE (during the first calculation of a
circular model). In these cases, no previous values exist from which to
calculate changes.

Examples:
DOLLAR(2.715)
DOLLAR(-I)
DOLLAR(.15)
Use the DELTA operation in a convergence test formula to calculate the
results of an interaction. Each time Multiplan encounters a DELTA
operation, it resets the internal DELTA value to O. By entering more than
one DELTA function, you can isolate the maximum change in a particular
part of the spreadsheet. To create a DELTA that applies only to the
differences of a part of the spreadsheet, bracket the cells with cells that
contain the DELTA function.
DOLLAR
(N)
Converts N to text showing a dollar amount, as in
$ of the Format Cells
command. Multiplan rounds N to 2 decimal places, places a 0 in the units
position if N
<
I, and adds a dollar sign ($) in front of the leftmost digit. If
N
<
0, Multiplan encloses N in parentheses.
