ssGetDataTypeIsFixedPoint

Determine whether registered data type is fixed-point data type

Syntax

extern int ssGetDataTypeIsFixedPoint(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 whether it is fixed-point.

Description

This function determines whether a registered data type is a fixed-point data type:

• This function returns TRUE if the registered data type is fixed-point, and FALSE otherwise.

• If the registered data type is a pure Simulink^® integer, such as int8, this function returns TRUE.

• If the registered data type is ScaledDouble, this function returns FALSE.

Requirements

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

• To build an S-function that utilizes this function, you must compile it using the mex function with -lfixedpoint argument. For more information, see Create MEX Files.
