pm_dateTime::getCountLeapYears Interface Reference

Generate and return the number of leap years within the closed year interval [since, until] where since represents the origin year, and until represents a later year after since. More...

Detailed Description

Generate and return the number of leap years within the closed year interval [since, until] where since represents the origin year, and until represents a later year after since.

Parameters
[in]until: The input scalar or array of arbitrary rank of type integer of default kind IK, containing the Gregorian Calendar year up to which the number of leap years since since must be returned.
If until < 0, then the number of leap years from the negative year until January, 1, 1 is returned.
[in]since: The input scalar or array of the same shape as until of the same type and kind as until, containing the Gregorian Calendar year that marks the beginning of the period within which the number of leap years must be counted.
(optional, default = 1_IK, i.e., the origin of the Gregorian Calendar.)


Possible calling interfaces

use pm_kind, only: IK
integer(IK) :: countLeapYear
countLeapYear = getCountLeapYears(until)
countLeapYear = getCountLeapYears(until, since)

Warning
The condition 0 < since < until must hold for the input argument values.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.
The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.
Remarks
The procedures under discussion are elemental.
The interface of this generic interface is intentionally defined to have until as the first input argument (as opposed to since).
This is to ensure the purity of the procedures under this generic interface.
Making until optional would require a call to the impure Fortran intrinsic date_and_time().
