BloombergLP::bbldc::CalendarBus252::yearsDiff

Return the (signed fractional) number of years between the specified beginDate and endDate according to the BUS‐252 day‐count convention with the specified calendar providing the definition of business days. If beginDate <= endDate, then the result is non‐negative. The behavior is undefined unless calendar.isInRange(beginDate) and calendar.isInRange(endDate). Note that reversing the order of beginDate and endDate negates the result; specifically, |yearsDiff(b, e, c) + yearsDiff(e, b, c)| <= 1.0e‐15 for all calendars c and valid dates b and e.
