I think that's the eventual plan, but until C++0x features are available (and the TR authors think they shouldn't be used yet), casts from decimal float types to generic float types must use conversion functions. In addition I couldn't get conversions from decimal float to long long to work without allowing otherwise invalid conversions to float, so currently those also need function calls. In addition, support for decimal floating-point constants is optional. Janis
