Check usage of floating-point expressions in Stateflow charts
Guideline: jc_0481: Use of hard equality comparisons for floating point numbers in Stateflow®
Identify equal to operations(
==) in expressions where at
least one side of the expression is a floating-point variable or
This check requires a Simulink® Check™ and Stateflow license.
This check does not include sub-checks because the MAB modeling guideline provides only one sub ID.
For reference, the MAB guideline sub ID(s) that are recommended for use by the NA-MAAB and JMAAB modeling standards organizations are:
NA-MAAB — a
JMAAB — a
Results and Recommended Actions
|Expressions use equality comparison
operations(||Modify the specified expressions to avoid equality comparison operations between floating-point expressions.|
|The Model Advisor could not determine the data types in expressions with equality operations.||Typecast the specified expressions explicitly to allow Model Advisor to determine the data types.|
