Documentation/How Tos/Calc: AND function

AND

Returns TRUE if all the arguments are considered TRUE, and FALSE otherwise.

Syntax:

AND(argument1; argument2 ...argument30)

argument1 to argument30 are up to 30 arguments, each of which may be a logical result or value, or a reference to a cell or range.

AND tests every value (as an argument, or in each referenced cell), and returns TRUE if they are all TRUE. Any value which is a non-zero number or text is considered to be TRUE.

Example:

If cells A5:B8 all contain TRUE, cell C2 contains =TRUE() and cell C3 contains "dog":

AND(2<4;A5:B8;C2)

returns TRUE.

AND(2<4;FALSE)

returns FALSE.

AND(C2:C3))

returns TRUE.
