I have this error whenever I try to define a fixed interval. How could I solve it?

What should I do here?

[Chidvi Modala]

I am unable to reproduce the error.

Which version of MATLAB are you using? And Is the value considered for pi is default(3.1416) or did you declare a variable named 'pi'?

[Mohamed Saleh]

I am using 2019b.

pi is default. No matter any other value or even 2 values for both ends, it gives me the same error.

Could you please try the following and copy paste the result?

It wants a license for Fixed-Point Designer to permit you to do those operations.
