Is this a bug?

[Charles Pegge]

Even after a number of repeats, it does not happen.

Could you try inserting a cls here:

Code: [Select]

    a = ltrim rtrim Input ' per togliere caratteri da input tipo CR
    if a=0 then exit do
cls
    b = sqrt(a)


[Nicola]

First of all thank you for the time you are dedicating to me ...
Unfortunately it also happens to me by entering CLS. I tried on both a 64bit and a 32bit.
See the attached file. I recorded the inputs until the weird characters come out.

Hi Nicola,

Your mp4 seems to be blank.

But there is nothing obvious wrong with your program, and I don't think anyone here has encountered that kind of problem with console outputs. I can only suggest stripping down the program to find out more about what causes this bug on your system.

the video is compressed with x264. Try using a video player that supports it. I use MPC-HC

[Charles Pegge]

Ok, mpc works.

@Nicola
I would like to help in determining what the problem is, what are the specs of your computer and OS?
I can't reproduce the problem on my PC, could you attach the exe that produces the problem?

[Nicola]

@jack
see attachments.

As I wrote before, I tried both compiling for a 32 bit and for a 64 bit. In both cases there is the same drawback. The 32-bit I tried it on a 32-bit win7 operating system.
This is for 32bit

Try this prog and see if there are any problems with it:

Code: [Select]

uses console
int i
double r
print "integer square roots" cr cr
for i=1 to 1000
  r=sqr(i)
  if frac(r)=0.0
    print i tab r cr
  endif
next
wait

It also demonstrates the reliability of frac()=0 to catch all the integer square roots

[jack]

I confirm that the exe that Nicola posted produces the problem
@Nicola
does the problem also happen when you "Run program directly" ?

[Charles Pegge]

Yes, I get that too. How did you compile it, Nicola? I've tried all the methods I could think of, but was unable to reproduce the bug.

[Nicola]

@Jack
Yes, even when it runs directly.

@Charles
Reply #22 --> it is OK. FRAC () works fine, as I had already seen in my program. At this point I think that the problem comes from INPUT.
Also interesting is the use of "tab" and "cr" ...

With Oxide. CTRL-F5 or CTRL-SHIFT-F5
I take o2 from github

OT

I tried to setup my Xfinity Flex stream box which is connected to an older LCD monitor without speakers. (have a sound bar) The setup program died after trying to optimize surroundasound for the HDMI signal.

Resolve was putting a newer monitor on it temporarily that had speakers to get through the setup.

Somehow this problem Nicola is having rings a similar bell.

@John
... I didn't quite understand what you mean, explain yourself better ...
a) am I using an old thing on a new pc? ...
b) am I using a new thing on an old pc?
c) ....?

[Charles Pegge]

Nicola,
You can try eliminating the ltrim rtrim.
Also try removing input() completely and set a to a fixed value. (ctrl-c will terminate)

[JRS]

c) Something is missing with your environment?
