The OR function is one of the logical functions. It is used to check if the logical value you enter is TRUE or FALSE. The function returns FALSE if all the arguments are FALSE.
The OR function syntax is:
OR(logical1, logical2, ...)
where logical1 is a value entered manually or included into the cell you make reference to.
To apply the OR function,
- select the cell where you wish to display the result,
- click the Insert Function icon situated at the top toolbar,
or right-click within a selected cell and select the Insert Function option from the menu,
or click the icon situated at the formula bar,
- select the Logical function group from the list,
- click the OR function,
- enter the required arguments separating them by commas,
Note: you can enter up to 265 logical values.
- press the Enter button.
The result will be displayed in the selected cell. The function returns TRUE if at least one of the argument is TRUE.
There are three arguments: logical1 = A1<>, logical2 = 34<>, logical3 = 50<>, where A1 is 12. All these logical expressions are FALSE. So the function returns FALSE.
If we change the A1 value from 12 to 2, the function returns TRUE:
