functions

The function

name

The general formula for the function

Example

Sum=SUM(A1:A6)=SUM(A1,D2,B

5 )

Find the total range

Find the sum of the values separate

Average

Average(A1:A6)=

Find the mean

Count=Count(A1:A6

)

To calculate the number of digits in

a range

Maximum Value

=Max(A1:A6) Maximum value within the range

Minimum Value

=Min(A1:A6)The minimum

value within the range

The general formula for the function

Purpose

=POWER(A1 ;2)

Function of power or exponent

=SQRT(A1) Returns the square root

=INT(A2)Approximation to the nearest

integer

The most important mathematical functions

The general formula for the function

Purpose

=Date)( Insert the date

=Today)( Return today's date

=Now)( The return of today's date

and the current time

The most important functions of the date and

time

The general formula for the

functionPurpose

=LEN(D4) Calculates the number of

characters in the cell

=TRIM(A4) Reduce the blanks for the single digits

=UPPER(F6) Transition from small to large

=LOWER(F7) Transition from large to small

The most important functions textual

The most important functions of the logic Function of IF

=IF(logical_test ; value_if_true; value_if_false)

Example :

=IF(A1>=60;”YES”;”NO”)
