Description
Returns the closest value to a specified value within a specified range.
EnsureRange returns a value that is guaranteed to be within a specified range.
AValue is the value you want as long as it is in range. If AValue is in range, EnsureRange returns AValue.
AMin is the minimum acceptable value. If AValue is less than AMin, EnsureRange returns AMin.
AMax is the maximum acceptable value. If AValue is greater than AMax, EnsureRange returns AMax.
