Return fractional slope of registered data type
extern double ssGetDataTypeFracSlope(SimStruct *S, DTypeId dataTypeId)
SimStruct representing an S-function block.
Data type ID of the registered data type for which you want to know the fractional slope.
Fixed-point numbers can be represented as
real-world value = (slope × integer) + bias,
where the slope can be expressed as
slope = fractional slope × 2exponent.
This function returns the fractional slope of a registered fixed-point data
type. To get the total slope, use
For power-of-two scaling, the fractional slope is
If the data type has trivial scaling, including data types
double, the fractional slope is
If the registered data type is
ScaledDouble, the fractional slope returned is that of the nonoverridden data type.
This function errors out when
To use this function, you must include
fixedpoint.c. For more information, see Structure of the S-Function.
