PRODUCT(number1 [,number2] [..])

Returns the product of all the numerical values.

number1	The first number.
number2	(Optional) The second number.

REMARKS

* You can include logical arguments such as true or false. True =1, False=0.
* Arguments that are just numbers are included.
* Arguments that are just numbers passed as text ("3") are included. See Example 15.
* Arguments that are just logical values are included. True evaluates to 1. False evaluates to 0. See Example 16.
* Arguments that are just text are excluded. See Example 18.
* Arguments that are cell ranges containing zeros are included. See Example 9.
* Arguments that are cell ranges containing dates are included. See Example 12.
* Arguments that are cell ranges containing hidden cells are included.
* Arguments that are cell ranges containing error values are excluded. See Example 14.
* Arguments that are cell ranges containing logical values are excluded. See Example 11.
* Arguments that are cell ranges containing text are excluded. See Example 10.
* Arguments that are cell ranges containing empty cells are excluded.
* Arguments that are arrays containing logical values are excluded. See Example 20.
* Arguments that are arrays containing text are excluded. See Example 19.
* You can have a maximum of 255 arguments.
* You can use the SUMPRODUCT function to return the sum of the product of one or more arrays of values.
* You can use the DPRODUCT function to return the product of the values in a column that satisfies multiple conditions.
* You can use the PRODUCTVISIBLE - User Defined Function to exclude hidden cells.
* You can use the AGGREGATE and SUBTOTAL functions to return the product of all the numerical values.
* This is similar to the AVERAGE, COUNT, MAX, MIN and SUM functions.

1 - What is the product of the values (1,2,3).
2 - What is the product of the values (1,2,3,0). Zeros are always included.
3 - What is the product of the values (-2,-3,4,5,6).
4 - What is the product of the values in the array {-2,-3,4,5,6}.
5 - What is the product of the values in range "B1:B3".
6 - What is the product of the values in range "B1", "B2" and "B3".
7 - What is the product of the values in range "B1", "B2", "B3" and "B4". B4 is empty. Empty cells are always excluded.
8 - What is the product of the values in range "B1", "B2", "B3" and "B5". B5 is zero so this gets included.
9 - What is the product of the values in range "B1", "B2", "B3" and "B6". B6 is text so this gets excluded.
10 - What is the product of the values in range "B1", "B2", "B3" and "B7". B7 is a logical value so this gets excluded.
11 - What is the product of the values in range "B1", "B2", "B3" and "B8". B8 is a logical value so this gets excluded.
12 - What is the product of the values in range "B1", "B2", "B3" and "B9". B9 is a date so this gets included as a date serial number.
13 - What is the product of the values in the named range that refers to the range "B1:B3".
14 - What is the product of the values in range "B1", "B2", "B3" and "B10". B10 contains an error so that gets returned.
15 - What is the product of these values (2, "3"). Text values that are actually numbers are included.
16 - What is the product of these values (2, TRUE). Logical values passed as arguments are included. TRUE is replaced with 1.
17 - What is the product of these values (2, FALSE). Logical values passed as arguments are included. FALSE is replaced with 0.
18 - What is the product of these values (2, "some text"). Text values passed as arguments are excluded.
19 - What is the product of the values in the array {2, "some text"}. Text values inside arrays are excluded.
20 - What is the product of the values in the array {2, TRUE}. Logical values inside arrays are excluded.
