I think you are mixing a lot of different things: - When storing a amount of money in memory, you store it in a Long integer in 1/10th of cents. For example, storing 1234,56€ will be stored as 1234560. - When displaying an amount of money, you use Format$(), or your own function. - When getting an amount of money from the user, you have to convert a string into an amount of 1/10th of cents. - When getting an amount of money from the outside, or exporting an amount of money to the outside, you must use an standard exchange format based on a string. So I don't see any problem with that. Why are you talking about telephone seconds? We are talking about money, aren't we? Or there is something I didn't understand? -- Benoît Minisini ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ Gambas-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/gambas-user
