How many type conversion are there in the code?

How many type conversion are there in the following code:

#include<stdio.h>
int f(int x)
{
    retu (float)x;
}
int main()
{
    float x = f(5L);
    retu 0;
}

In function f(), the retu value is promoted from int to float. In main(), the argument of f() is promoted from int to long, and int is again promoted to float.

Is it correct that there are three type conversions (promotions)?
