Logical Functions
Logical functions can be used to handle conditional information.
And
| Description | Returns TRUE if all its arguments are TRUE; returns FALSE if any argument is FALSE. |
|---|---|
| Remark | The arguments must evaluate to TRUE or FALSE.
NOTE. The And function can take more than two arguments as input. |
| Example | Ex. AND(2+2=4, 4+0=4, 2+3=6) – returns FALSE.False: |
False
| Description | Returns the logical value FALSE. |
|---|---|
| Remark | You can also type the word FALSE directly onto the worksheet or into a formula; it is interpreted as the logical value FALSE |
If
| Description | Takes three arguments as input. Returns the second argument if the first evaluates to TRUE. Otherwise returns the third argument. |
|---|---|
| Remark | The first input must evaluate to TRUE or FALSE. |
| Example | Ex. if({OrderDetail.Price}= 0,’FREE’,{OrderDetail.Price}) – returns FREE if the price is 0, otherwise it returns the price. |
Not
| Description | Reverses the value of its argument. |
|---|---|
| Remark | Argument should evaluate to TRUE or FALSE. |
| Example | Ex. Not(FALSE) – returns TRUE. |
Or
| Description | Returns TRUE if any argument is TRUE. |
|---|---|
| Remark | The arguments must evaluate to logical values such as TRUE or FALSE. NOTE. The ‘Or’ function can take more than two arguments as input. |
| Example | Ex. OR(2+2=4, 4+0=8, 2+3=6) – returns TRUE. |
Switch
| Description | This function should be used instead of placing if() functions inside of if() functions.
Takes any even number of inputs arguments. |
|---|---|
| Remark | The 1st argument will be the test value to compare to.
The 2nd argument will be returned if none of the comparisons return true. The 3rd, 5th, 7th… arguments will be compared to the 1st argument. When the first match occurs the following argument will be returned. For example if argument 3 matches argument 1 then the 4th argument will be returned. |
| Example | Ex. Switch({Categories.CategoryName},”NOT FOUND”, “Beverages”, “Drink up!”, “Condiments”, “Enhance”, “Confections”, “Sweet Tooth”) – returns a string based on the Category Name. |
True
| Description | Returns the logical value TRUE. |
|---|---|
| Remark | You can also type the word TRUE directly onto the worksheet or into a formula; it is interpreted as the logical value TRUE. |
