Stateflow User's Guide

Using Fixed-Point Data in Stateflow

In What Is Fixed-Point Data? you learn the theory behind fixed-point numbers. In this section you learn how Stateflow implements these numbers in the following topics:

• How Stateflow Defines Fixed-Point Data -- Describes the parameters that Stateflow uses to define fixed-point data.
• Specifying Fixed-Point Data in Stateflow -- Tells you where and how to specify fixed-point data in Stateflow.
• Fixed-Point Context-Sensitive Constants -- Tells you how to specify fixed-point constants that take their data type from the context in which they are used.
• Tips for Using Fixed-Point Data in Stateflow -- Gives you guidelines for using fixed-point data in Stateflow.
• Overflow Detection for Fixed-Point Types -- Tells you how to detect errors that result from exceeding the numeric capacity of fixed-point numbers.
• Sharing Fixed-Point Data with Simulink -- Tells you how to specify fixed-point data in Simulink that it shares with Stateflow as input from Simulink and output to Simulink data
