Conversion Function Instantiations
The RT_FIXED_OPERATORS package contains instantiations of functions
that represent conversion of values to and from a fixed-point type. The
appropriate generic function from the
SA_FIXED_GENERICS package is
chosen to instantiate the function. The name of the instantiated function
follows a convention that indicates what type of conversion is to be done.
Table 3-10 defines the naming convention for conversion functions.
Table 3-10. Conversion Function Naming Conventions
Conversion Type Name 1
Fixed to RT_INTEGER RT_YYxx_I
Fixed to RT_INTEGER (truncation) RT_YYxx_It
Fixed to RT_INTEGER (round) RT_YYxx_Ir
Fixed to RT_LONG_INTEGER RT_YYxx_LI
Fixed to RT_LONG_INTEGER (truncation) RT_YYxx_LIt
Fixed to RT_LONG_INTEGER (round) RT_YYxx_LIr
Fixed to RT_BOOLEAN RT_YYxx_B
Fixed to RT_FLOAT RT_FLOAT
RT_INTEGER to Fixed RT_YYxx
RT_LONG_INTEGER to Fixed RT_YYxx
RT_BOOLEAN to Fixed RT_YYxx
RT_FLOAT to Fixed RT_YYxx
RT_FLOAT to Fixed (truncation) RT_YYxxt
RT_FLOAT to Fixed (round) RT_YYxxr
Fixed to Fixed (different types) RT_YYxx
Fixed to Fixed (different types, truncation) RT_YYxxt
Fixed to Fixed (different types, round) RT_YYxxr
Fixed to Fixed (same type, no-op cast) YYxx
1 YY indicates the short name of a fixed-point type xx is the two-digit radix.
