functx:total-hours-from-duration

The total number of hours in a dayTimeDuration

Description

The functx:total-hours-from-duration function returns the total number of hours in $duration. If it is an uneven number of hours, it will return a fractional part. This function is different from the built-in fn:hours-from-duration function because the latter will normalize the value and only give you the remainder number of hours between 1 and 24. For example, fn:hours-from-duration(xs:dayTimeDuration("PT26H30M")) will return 2, while functx:total-hours-from-duration(xs:dayTimeDuration("PT26H30M")) will return 26.5. If $duration is the empty sequence, the empty sequence is returned.
