Syntax Description
WORKDAY(start_date; days;
holidays)
Returns a date number that can be formatted as a date. You
then see the date of a day that is a certain number of
Workdays away from the start_date. Holidays (optional) is
a list of holidays. Enter a cell range in which the holidays are
listed individually.
YEAR(number) Returns the year as a number according to the internal
calculation rules. Number shows the internal date value for
which the year is to be returned.
YEARFRAC(start_date; end_date;
basis)
YEARS(start_date; end_date;
type)
Logical functions
Returns a number between 0 and 1, representing the fraction
of a year between start_date and end_date. Start_date and
end_date are two date values. Basis is chosen from a list of
options and indicates how the year is to be calculated.
Calculates the difference in years between two dates: the
start_date and the end_date. Type calculates the type of
difference.
Use the logical functions to test values and produce results based on the result of the test. These
functions are conditional and provide the ability to write longer formulas based on input or output.
Table 40: Logical functions
Syntax Description
AND(logical_value_1;
logical_value_2;
...logical_value_30)
Returns TRUE if all arguments are TRUE. If any element is
FALSE, this function returns the FALSE value. Logical_value_1;
logical_value_2; ...logical_value_30 are conditions to be
checked. All conditions can be either TRUE or FALSE. If a range is
entered as a parameter, the function uses the value from the range
that is in the current column or row. The result is TRUE if the
logical value in all cells within the cell range is TRUE
FALSE() Set the logical value to FALSE. The FALSE() function does not
require any arguments.
IF(test; then_value;
otherwise_value)
Specifies a logical test to be performed. Test is any value or
expression that can be TRUE or FALSE. Then_value (optional) is
the value that is returned if the logical test is TRUE.
Otherwise_value (optional) is the value that is returned if the
logical test is FALSE.
NOT(logical_value) Reverses the logical value. Logical_value is any value to be
reversed.
OR(logical_value_1;
logical_value_2;
...logical_value_30)
Returns TRUE if at least one argument is TRUE. Returns the value
FALSE if all the arguments have the logical value FALSE.
Logical_value_1; logical_value_2; ...logical_value_30 are
conditions to be checked. All conditions can be either TRUE or
FALSE. If a range is entered as a parameter, the function uses the
value from the range that is in the current column or row.
TRUE() Sets the logical value to TRUE. The TRUE() function does not
require any arguments.
