Function
Category
Description
AVERAGE( number1 [,
number2 , number3 , ...])
Statistical
Calculates the average of a collection of
numbers, where number1, number2, and so forth are
either numbers or cell references. Only number1
is required. For more than one cell reference or
to enter numbers directly into the function, use
the optional arguments number2, number3, and
so forth.
COUNT( value1 [, value2 ,
value3 , ...])
Statistical
Counts how many cells in a range contain numbers,
where value1, value2, and so forth are text,
numbers, or cell references. Only value1 is required. For
more than one cell reference or to enter numbers
directly into the function, use the optional
arguments value2, value3, and so forth.
COUNTA( value1 [, value2 ,
value3 , ...])
Statistical
Counts how many cells are not empty in ranges
value1, value2, and so forth, or how many numbers
are listed within value1, value2 , and so forth.
INT( number )
Math & Trig
Displays the integer portion of a number, number .
MAX( number1 [, number2 ,
number3 , ...])
Statistical
Calculates the maximum value of a collection of
numbers, where number1, number2, and so forth
are either numbers or cell references.
MEDIAN( number1 [,
number2 , number3 , ...])
Statistical
Calculates the median, or middle, value of a
collection of numbers, where number1, number2 , and so
forth are either numbers or cell references.
MIN( number1 [, number2 ,
number3 , ...])
Statistical
Calculates the minimum value of a collection of
numbers, where number1, number2, and so forth
are either numbers or cell references.
RAND()
Math & Trig
Returns a random number between 0 and 1.
Math & Trig
ROUND( number , num_digits )
Rounds a number to a specified number of digits,
where number is the number you want to round and
num_digits specifies how many digits to which you
want to round the number.
SUM( number1 [, number2 ,
number3 , ...])
Math & Trig
Adds a collection of numbers, where number1 ,
number2 , and so forth are either numbers or cell
references.
For example, the AVERAGE function calculates the average value from a collection of
numbers. The syntax of the AVERAGE function is
AVERAGE( number1 ƒ[,ƒ number2 number3 ,ƒ...])
where number1 , number2 , number3 , and so forth are either numbers or cell references
to numbers. The following formula uses the AVERAGE function to calculate the average
of 1, 2, 5, and 8, returning the value 4:
=AVERAGE(1,ƒ2,ƒ5,ƒ8)
However, functions usually reference values entered in the worksheet. So, if the
range A1:A4 contains the values 1, 2, 5, and 8, the following formula also returns a
value of 4:
=AVERAGE(A1:A4)               Search JabSto ::
