and() Function
This function may not be compatible with all features of Appian. For details, see the Feature Compatibility section below.

Function

and( value )

Returns true if all inputs are true; returns false if at least one input is false.

Parameters

Keyword Type Description

value

Boolean

A value or array of values that must be true for the function to return true.

Returns

Boolean

Usage considerations

Casting and returning boolean values

  • Arguments are cast to Boolean before and() evaluates.
  • As soon as the returned value of a value evaluation returns false, the function returns false.

Evaluation order and performance

  • Multiple arguments are evaluated left-to-right.
  • By keeping common conditions on the left and complex edge cases on the right, you can improve function performance. That way, if an earlier, simple function returns false, evaluation of the later edge cases never occurs.

Null and empty arrays

  • Null values that are part of input arrays are filtered out before evaluation.
  • Empty arrays evaluate to true.
  • Empty text strings in a text array evaluate to false, but empty text strings in an array with multiple data types are considered null values and are filtered out before evaluation.

Examples

Use functions to Pass Multiple Logical Values:

and(isleapyear(1996),isleapyear(1997)) returns false

Pass an Empty Array:

and({}) returns true

Pass an Array of Numbers:

and(1,2,"",3) returns true

and(0,1,2,"",3) returns false because 0 casts to false
