Re: int-function: programming error or bug?

Aron Brunner scripsit:

This line is your problem.  Floating-point numbers do *not* behave like
mathematical real numbers; in particular, there is no guarantee that
a loop like this will iterate the correct number of times or have the
values you expect.

Instead, work your problem in terms of integers:

    for (alfa = 86; alfa <= 92; alfa = alfa + 1) {

and divide by 10 just before doing the output.
