desing question about dictionaries

xdm

Hi Zeroc

In the latest version of ice-programing book Ice-2.0.0
in slice maping section. I read that dictionaries can't not
use floating points values as key type.

I'm developing a PriceService with it's main target is to
maintaing diferent price list for a catalog of products that's
implementing in a diferent Ice service.

I want that my PriceService can index the Prices but my price
is defined as a double and like double values can't no be the key
type of dictionaries i need other aproach to solve this trouble

Now re reding Ice progrmaing book i see that struct of basic types can
can be used as key type of dictionaries and i think that i can
change my price type fron double to a struct like this

                    struct PriceValue
                    {
                        long integerPart; 
                        long fractionPart;
                    };
                    
                    dictionary <PriceValue,ProductPrice>PriceValueMap;

Can any body say me if this is a good aproach or if there are
any better soluttion for this trouble?

thanks to all you
and congratulations Zeroc team for Ice-2.0.0
