That code produces odd results for me (patch 2)

1.1000000238418579
1.1000000238418579

Memblock float commands also do not work properly.

The variables seem to hold the correct values (run the program through in step through mode and watch the values), but they are printed incorrectly. So hopefully this is just a problem with the Print command and not with floats.

Note that the Text command also prints an incorrect value (1.1000000238418579 rather than 1.1)

Isn't the FPU on AMD processors more/less accurate than Intel ones?

I've got a AMD computer (as well as 2 Intel ones), so it'll be interesting to see what happens.

This is same problem as my post and what I have now read on RGT forums. It works on some PC's and not others. I am at work at moment (we only use Windows NT - Urrghhh!)

At home I have 2 PC's. One with AMD Athlon XP 2000 which I know shows incorrect numbers, but I also have a PC with P3 500 processor. I will install dbpro on it and see what happens between the various patches.

I know that there is a problem with Print.
On AMD K6 2 500 (192 Mb, Win 98SE, ALI Chipset) I got the right value
On AMD Tbird 1200 (512 Mb, Win 98SE, Via Chipset) I got the wrong one
Probaly this depends on CPU or Chipset. So nobody here smokes grass or crack.

Viktor,

Raven is using the Demo Version2. Not Full Version + Patch 2.

What are you using? Demo1, Demo2 or full verswion patched to Patch 2?

Also get the same incorrect value on my AMD processor. Obviously its not processor related.

I think the problem is that PRINT can only handle double floats, and perhaps a# is just a normal float...

I tried this:

a#=1.25
b#=1.5
c#=1.75
d#=1.33
e#=1.66

Printing them I got:
a# 1.25
b# 1.5
c# 1.75
d# 1.3300000429153442
e# 1.6599999666213989

It sorta freaks when the fractional numbers cannot be divided equally in 1

Speck,

What is the filesize of your core.dll file in

C:\Program Files\Dark Basic Software\Dark Basic Professional\Compiler\plugins

if it's 106,496 (bytes) you are still patch 1 (you need to run updater) D:\Program Files\Dark Basic Software\Dark Basic Professional\Updater\Updater.exe

if you are patch 2 the filesize will be 110,592 (bytes)

if I put the patch1 core.dll file and leave the others alone, I also get 1.1.

So I am guessing your DB PRO didn't patch correctly. When that happens, you need to run the updater program.

Drat, hit the wrong button. Anyway as I was saying.. Some confusion on that post Zep.

On my Celeron system it was running the core.dll from patch 1 (which I thought was upgraded by reinstalling the demo), my AMD is running a nice fresh install of the demo with patch 2.

I copied my core.dll from Demo Patch1 over to the workstation using Demo patch2, and now the numbers are displayed correctly.

Zep,

Core from Patch1 is 106496 9/19/2002
Care from Patch2 (Clean install) is 110592 10/21/2002


What I was getting at, is if someone's DB didn't patch properly with the Core.dll, may as well leave as it is. Of course, I don't know if anything else was changed on Core from Patch1 and Core from Patch2, so it may close this bug, and open another.

all you have to do to get it to patch properly (if you have the Full Version) is run Updater.exe. Sometimes, when running the patch, updater.exe doesn't run and you have to run it manually.

I give up!
De-installed dbpro on 2 differenct pc's and re-installed from scratch.
pc1 = Win98,P3 500
pc2 = WinXP,Athlon XP 2000

Fresh install of dbpro with no patches, both pcs give correct answer when simply saying:
print 2.55 : wait key

After patch 1, both still give correct answer

After patch 2, pc1 still correct but pc2, my main pc, gives incorrect answer.

Anyone see any logic?

As far as I can tell, everything patched correctly with no errors.

Well I run the current demo (fresh install on new machine) for right now, and get correct results using the core.dll from the 1st demo release.

It would be nice if someone from DBS could comment.
