/**
* Implementation of ACT/360.
*
* Calculates the day count by calculating the actual number of days between startDate and endDate.
*
* A fractional day is rounded to the approximately nearest day.
*
* The day count fraction is calculated using ACT/360 convention, that is, the
* day count divided by 360.
*
* This day count convention is sometime called Money Market basis.
*
*
* -
* The method {@link #getDaycountFraction(LocalDate, LocalDate) getDaycountFraction} corresponds to the implementation of the "ACT/360 method" of Excel function YEARFRAC, i.e., YEARFRAC(startDate,endDate,2).
