BloombergLP::bbldc::PeriodDayCountUtil::yearsDiff

Synopses

Declared in <bbldc_perioddaycountutil.h>

Return the (signed fractional) number of years between the specified beginDate and endDate according to the specified day-count convention with periods starting on the specified periodDate values and each period having a duration of the specified periodYearDiff years (e.g., 0.25 for quarterly periods). If beginDate <= endDate then the result is non-negative. The behavior is undefined unless periodDate.size() >= 2, the values contained in periodDate are unique and sorted from minimum to maximum, min(beginDate, endDate) >= periodDate.front(), max(beginDate, endDate) <= periodDate.back(), and isSupported(convention). Note that reversing the order of beginDate and endDate negates the result; specifically, |yearsDiff(b,e,pd,pyd,c) + yearsDiff(e,b,pd,pyd,c)| <= 1.0e-15 for all dates b and e, periods pd, and year fraction per period pyd.
