Usage
Less Than is strictly a dyadic function, there must be a value on both sides of the operator or a VALENCE ERROR will occur. Less Than tests the value(s) on the left against the value(s) on the right, and returns 1 for each value where the value on the left is lower than the value on the right, 0 otherwise.
