Method Get():minus() Foundation
Tests whether a negative numeric value was entered.
:minus() --> lNegativeValue
When a Get object has input focus and is associated with a numeric value, the method :minus() returns .T. (true) when a negative number has been entered into the edit buffer. In all other cases :minus() returns .F. (false).
When entering numbers, the method :minus() tests whether a minus sign was entered as the first character, thereby indicating a negative value.
