This struct provides a namespace for a suite of pure functions that compute values based on dates according to enumerated day-count conventions.
Declared in <bbldc_basicdaycountutil.h>
struct BasicDayCountUtil;| Name | Description |
|---|---|
daysDiff | Return the (signed) number of days between the specified beginDate and endDate according to the specified day-count convention. The behavior is undefined unless isSupported(convention). If beginDate <= endDate then the result is non-negative. Note that reversing the order of beginDate and endDate negates the result. |
isSupported | Return true if the specified convention is valid for use in daysDiff and yearsDiff, and false otherwise. |
yearsDiff | Return the (signed fractional) number of years between the specified beginDate and endDate according to the specified day-count convention. If beginDate <= endDate then the result is non-negative. The behavior is undefined unless isSupported(convention). 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 dates b and e, and day-count conventions c. |
