I am trying to do a simple division operation in stateflow like a=5/2 but the output is coming to 2 instead of 2.5 The data type of a is double. Its rounding the decimal digits and giving me only the integer part. Pls help

I believe typecasting both dividend and divisor as double should do the job.
{
a = double(5)/double(2);
}
Not sure whether this the usual approach.

Thanks Vishal for the answer. But we don't need to typecast both numerator as well as denominator. Typecasting only numerator will do the job. And if we are giving num and deno as input variables from simulink then keeping the data type of those parameters as double will also give write answer

But still the question remains that why stateflow is doing floor(a/b) and giving 2 instead of 2.5. Is typecasting only solution in this case or is there a specific setting where we can avoid rounding of the integers. Simulink works fine in this case. Problem is only in stateflow.

Instead, you can try the following assignment, a:=5/2;
This overrides the floor(a/b) behaviour in stateflow and gives you the desired result which is entirely dependent on the datatype of a. In this case you will get a = 2.5
