# [Frama-c-discuss] Value Analysis - assertion, slevel and sqrt function

• Subject: [Frama-c-discuss] Value Analysis - assertion, slevel and sqrt function

```Hi,

We have been working with Value Analysis Plugin (version Carbon) with a
real case study.

In the Frama-C Value Analysis plug-in 20110201 (Carbon), Section 7.1.2 Case
analysis, page 64, we saw the following example:

x = Frama_C_interval(-10,10);
//@assert x <= 0 || x >= 0 ;
y = x*x;

The example shown that if an assertion is a disjunction, then the reduction
of the state by the assertion may be computed independently for each
disjunct.

In our case study, the program calls the sqrt function 2 times with the
following parameters:
sqrt(a*a + b*b + c*c);

Our doubt is how to define the argument of the option slevel, i.e., the
number of times that is necessary to deal with the assertion.

It has worked with the minimum value equal 32:
>> frama-c -val sqrt.c /usr/share/frama-c/builtin.c
/usr/share/frama-c/math.c -slevel 32

We have 2 doubts:
1- how to define the correct value to the argument of the option slevel;
2- the program called the function Frama_C_show_each to verify the value of
the variables, but we have observed that the function is called several
times. Why does it occur?

The source code and the log are attached bellow.

Best Regards,
Rovedy, Nanci, Luciana
