Logical functions
The logical functions evaluate relationships and return true or false results.
For example, the IF function looks at a condition, such as whether the
contents of B13 = 500, and returns a true or false answer (true=l, false=0).
Mathematical functions
Mathematical functions provide common mathematical formulas. For
example, INT (Integer) truncates a value to the nearest whole number. The
arguments for mathematical functions are either values or addresses of cells
that contain values.
Print functions
The print functions retum the name of the current file, the current page, and
the number of pages. For example, PAGE returns the current page number
and can be inserted in headers and footers for numbering pages.
Statistical functions
Statistical functions provide formulas for common statistical calculations. For
example, MAX returns the largest value in a list. The arguments for statistical
functions consist of either values or addresses of cells that contain values.
String functions
- A string _s a series of characters. Stnng funcuons extract text (including -_
numbers) or retutrh values based on the text. At least one argument in each
string function is a text string.
Time and date functions
The time and date functions allow you to enter times and dates in serial form,
which is a form that Spreadsheet can understand. For example, you can use
the DATEVALUE function to create the appropriate serialized date such as
33988 for January 20, 1993. These functions are most useful in formulas
where the time and date are calculated r',ither than entered as a constant.
Trigonometric functions
" Trigonometric functions provide formulas for common trigonometric
calculations. The arguments for-trigonometric functions are either values or
addresses of cells that contain values.
