IDE Strange Behaviour : Division By 0
« on: September 23, 2019, 09:06:43 am »
Hello everyone!
Try to type following into your QB64 IDE
Code: QB64: [Select]
  1. const a = 14 \ 3
  2.  

Reply to this, if you get "Division by 0 error".
Remember, I am using integral division "\"

Hi Ashish, what version QB64 are you using? (assuming you are getting a division by 0 error, I am not with QB64 1.3 on Windows 10)

I'm not getting an error either.  When I print a, I get a value of 4.

There is no problem with printing the value. The problem is with just one line - "CONST a = 14 \ 3".

DON'T COPY AND PASTE THAT CODE IN IDE!!!!
I already said try to *type* that line in QB64 IDE.

I am using QB64 V1.3 Dev Build [git 729557f]

Hi Ashish. The ide crashes after entering the command. Windows reports that the program has stopped working. If i start it again and clicking YES for restoring previous program, IDE crash again. Version 1.3 96937f0

This has been fixed in the development version, and in my personal repo (for those who have cloned it).

I am using Dev build, and that's the reason I can see the reason of the error.

What version/OS?  The IDE is picking up the glitch and reporting it as a standard error for me, as illustrated in the screenshot below.  There's a difference in our systems somewhere, but what the heck is it, to make it behave differently for you?

You must not have the latest dev build, which corrects the issue.  As you can see from your screenshot, and mine (which I just downloaded a few moments ago for testing), the version numbers don't match at all.

At this point, all I can suggest is to grab a fresh copy from the repo and see if the glitch persists for you.  If so, are you on Linux/Mac, or Windows?  I don't have a clue where to start debugging a glitch which I can't seem to reproduce.  :(

I have version 1.2, I see what Steve sees. However, if you keep typing, it goes away.
You type up to the \
you see the error
you type the 3, now its gone.
Is that a bug?

Nope.  That's the IDE telling you what it should be telling you -- you're trying to divide by zero; finish filling in that formula properly.  ;)
