Syntax a while loop

I am not sure I have the syntax right on my while loop: And I am taking the absolute value with the abs command.

            EA1 = pi / 4;
            diff = 1;
            while (abs(diff) > 0.000001)
                diff = (EA1 - e * sin(EA1) - MA) / (1 + e * cos(EA1));
                EA1 = EA1 + diff;
            end

That syntax is fine. You do not need the () around the condition but it does not hurt.
