One more question about intervals

Hi,

after some work with intervals I got a little further. Now I have two
questions:
a) Is there a datestyle where > 24 hours is not represented as a 1 but as
   24 hours (or 48 or whatever)?
b) Can Postgres do calculations like one hour does cost 100 Euro, how many
   Euro were worked for?

Cheers,

Konstantin
