yearsDiff(
    bdlt::Date const& beginDate,
    bdlt::Date const& endDate) const override;

Description

Return the (signed fractional) number of years between the specified beginDate and endDate as per the CONVENTION template policy. If beginDate <= endDate, then the result is non‐negative. Note that reversing the order of beginDate and endDate negates the result; specifically, |yearsDiff(b, e) + yearsDiff(e, b)| <= 1.0e‐15 for all dates b and e.

Return Value

the signed fractional number of years between the dates
