Number list

This function returns a number list in l that validates predicate.

Argument predicate is a boolean expression, where ^ is used for referencing numeric values in argument l.


filterByPredicate(number list l, boolean expression predicate) #Output: Number list



Parser expressionDescription


filterByPredicate([1, 2, 3, 4], ^ > 2)


This example returns a number list of values greater than 2 : [3, 4]


filterByPredicate([1, 2, 3, 4], remainder(^, 2) = 0)
