between(value,min,max)
Returns Boolean true if the value is greater or equal to min and less than max. The comparison method is based on the type of value; numerical, lexical, string and set comparisons are chosen as needed.
The logic is:
((value >= min) & (value < max))
Thus between() is true if value==min but false if value==max.
If $MyNumber is 7, then:
$MyBoolean = between($MyNumber, 1, 5); is false
$MyBoolean = between($MyNumber, 1, 9); is true
More realistically the operator would be used in a query or a conditional expression:
if(between($MyNumber, 1, 5)){…}else{…}; would test as true and execute the code in the first conditional branch.
Do not use this operator for testing Date-type attributes directly. Either use days() instead or use between() with format() or Date.format() to create a suitable string values for testing.
In the query creation pop-ups of agent and Find dialogs this function is listed as "is between".
This replaces the legacy #between query operator.
