[wp-34s] h.mmss number entry

[ahagele]

I'm having difficulties entering numbers in the hh mm ss format.

The decimal to hhmm works fine with the H.MS function (e.g. 1.5 H.MS -> 1 30' 00"
However how do I enter 1 hr 30min?
The H .dd does give me nothing useful. Assuming a format of hhhhmmss.dd would mean entering 13000.00 H .d -> shows 13000
Entering 1.30 gives me 1.3

I just want a simple way to add time sheet data in the form of 1hr 15min + 3 hrs 35min + 2 hr 58min. Having the result back in hr and minutes.

Thanks for your help
