Syntax

extern double ssFxpConvertToRealWorldValue (SimStruct *S,
                                            const void *pVoidSrc,
                                            size_t sizeofSrc,
                                            DTypeId dataTypeIdSrc)

Arguments

S

SimStruct representing an S-function block.

pVoidSrc

Pointer to the value you want to convert.

sizeofSrc

Size in memory of the value you want to convert.

dataTypeIdSrc

Data type ID of the value you want to convert.

Description

This function converts a value of any registered built-in or fixed-point data type to a double.
