ssGetDataTypeBias - Return bias of registered data type

Syntax

extern double ssGetDataTypeBias(SimStruct *S, DTypeId
                                dataTypeId)

Arguments

S

SimStruct representing an S-function block.

dataTypeId

Data type ID of the registered data type for which you want to know the bias.

Description

Fixed-point numbers can be represented as

real-world value = (slope × integer) + bias.

This function returns the bias of a registered data type:

• For both trivial scaling and power-of-two scaling, 0 is returned.

• If the registered data type is ScaledDouble, the bias returned is that of the nonoverridden data type.

This function errors out when ssGetDataTypeIsFxpFltApiCompat returns FALSE.

Requirement

To use this function, you must include fixedpoint.h and fixedpoint.c. For more information, see Structure of the S-Function.
