There are two potential problems with this choice of a price type. First, xsd:double can be serialized in the scientific notation which would be an unusual way -of representing a price. Second, we would like to limit the number of +of representing a price. Second, we would like to limit the number of fraction digits in our prices to 2. Furthermore, we would like to always have two fraction digits, even if one or both of them are zeros, for example: 12.99, 12.90, 12.00. @@ -42,21 +42,45 @@ double-custom.cxx file described below. xml-schema.hxx - C++ types for XML Schema built-in types.
