expr does not "do" floating point numbers (decimal numbers).

Code:
bc -l

does.

Code:
 echo "1.356 * 1.2" | bc -l


The awk command does double precision (15 digits of floating point) as well.

Code:
echo "13 14.112" | awk '{print $1 * $2}'

PURPOSE

       To write formulas to the worksheet

NODE NAME

       Excel::Template::Element::Cell

ATTRIBUTES

       All attributes a CELL can have, a FORMULA can have, including the ability to be referenced using the 'ref' attribute.

EFFECTS

       This will consume one column on the current row.

USAGE

	 <formula text="=(1 + 2)"/>
	 <formula>=SUM(A1:A5)</formula>

	 <formula text="$Param2"/>

       In the above example, four formulas are written out. The first two have the formula hard-coded. The second two have variables. The third

       the latter form. Variables within parameters are the entire parameter's value.
