Hello,

I want to use condition like if (u ==1), IF block has single/double data type by default, so whenever I generate the code from simulink model, this condition shows u == 1.0F How can I change data type to Int or Boolean so in the autocode it will show u == 1.0 ??

Or any other way to implement if elseif condition where I could change the data type of if condition in Simulink?

Thanks in advance for your answer.

Try this, Use a Relational Operator block where you can specify any data type for the inputs. Specify the output data type as boolean which is the default. Feed this to the IF block where the condition is if (u)
