Hi Michael,

As a comparison, there are 24 functions that implement time -
date related functions, and 5 numeric functions:

        10.5.1 fn:years-from-duration
        10.5.2 fn:months-from-duration
        10.5.3 fn:days-from-duration
        10.5.4 fn:hours-from-duration
        10.5.5 fn:minutes-from-duration
        10.5.6 fn:seconds-from-duration
        10.5.7 fn:year-from-dateTime
        10.5.8 fn:month-from-dateTime
        10.5.9 fn:day-from-dateTime
        10.5.10 fn:hours-from-dateTime
        10.5.11 fn:minutes-from-dateTime
        10.5.12 fn:seconds-from-dateTime
        10.5.13 fn:timezone-from-dateTime
        10.5.14 fn:year-from-date
        10.5.15 fn:month-from-date
        10.5.16 fn:day-from-date
        10.5.17 fn:timezone-from-date
        10.5.18 fn:hours-from-time
        10.5.19 fn:minutes-from-time
        10.5.20 fn:seconds-from-time
        10.5.21 fn:timezone-from-time
        10.7.1 fn:adjust-dateTime-to-timezone
        10.7.2 fn:adjust-date-to-timezone
        10.7.3 fn:adjust-time-to-timezone

        6.4.1 fn:abs
        6.4.2 fn:ceiling
        6.4.3 fn:floor
        6.4.4 fn:round
        6.4.5 fn:round-half-to-even

I'm not saying that any of the time - date related functions are
nice-to-have, maybe they are vital for somebody's use case,
but I am saying that math functions are important,
especially, in my use case, rounding as specified by the IEEE
floating point standard.

But since I don't hear anybody seconding the motion, that is my
2p.  :-)
