Few days ago,I had a problem solving elementary equations in flash action script 3. I asked here and got an anwer ,I thank him very much.
I temporary fixed the program to replace any equation representing a straight line almost parallel to y axis by a new line completely parallel to y axis. Currently it seems that the fixed program finds the meeting point of 2 straight lines correctly if they are not parallel to each other.
Then , let me ask you my new question. If I use Matlab to solve the same problems , do I also need to do similar checking relating "cancellation of digits"?
Thanks in advance.
