Logical Boolean AND Operator (FPScript)

23.08.2021

Carries out a logical Boolean AND operation for two expressions.

Syntax

Expression1 And Expression2

The syntax of the And operator consists of the following elements:

Element

Description

Expression1

An expression that results in TRUE, FALSE or any numeric scalar value. For the numeric result, all values not equal to zero are taken to be TRUE.

Expression2

Same as Expression1.

Remarks

If one of the expressions returns a list, then the first element in the list is taken, as long as it is not also a list. Otherwise, the extraction process is repeated recursively. All other elements of the list are ignored.

The result is a Boolean value that results from the following Boolean table:

Expression1

Expression2

Result

FALSE

FALSE

FALSE

TRUE

FALSE

FALSE

FALSE

TRUE

FALSE

TRUE

TRUE

TRUE

You can link several operations together. The expressions are evaluated beginning from the left only up to the first expression, which returns FALSE.

If Expression1 or Expression2 is a quantity, then it has to have the SI dimension 1 and it will be transformed to the unit 1 before conversion.

Available in

FlexPro View, Basic, Professional, Developer Suite

Example

If Minimum(Signal) > 3 And Maximum(Signal) < 5 Then

     ...

End

Carries out a block of code if the signal lies in the range [3, 5].

1 And 2 Pi

Returns TRUE, since the unit Pi has the SI dimension 1 and 2 Pi transformed to the unit 1 results in the value 6.2831853, which is not equal to zero.
