Thank you!

hi,
today i use float in new version and result is weird

Code: Select all

For c = 1 To 10
  Debug 0.1 * c
  Debug 1 + ( 0.1 * c )
  Debug 2 + ( 0.1 * c )
  Debug 3 + ( 0.1 * c )
  Debug 4 + ( 0.1 * c )
  Debug 5 + ( 0.1 * c )
  Debug 6 + ( 0.1 * c )
  Debug 7 + ( 0.1 * c )
  Debug 8 + ( 0.1 * c )
  Debug 9 + ( 0.1 * c )
  Debug ""
Next

Code: Select all

RESULT:

Float are not exactly accurate, why is it wierd ?

[Falko]

Code: Select all

For c = 1 To 10
  Debug StrD(0.1 * c)
  Debug StrD(1 + 0.1 * c )
  Debug StrD(2 + 0.1 * c )
  Debug StrD(3 + 0.1 * c )
  Debug StrD(4 + 0.1 * c )
  Debug StrD(5 + 0.1 * c )
  Debug StrD(6 + 0.1 * c )
  Debug StrD(7 + 0.1 * c )
  Debug StrD(8 + 0.1 * c )
  Debug StrD(9 + 0.1 * c )
  Debug ""
Next

[Demivec]

Code: Select all

For c = 1 To 10
  Debug StrD(0.1 * c)
  Debug StrD(1 + 0.1 * c )
  Debug StrD(2 + 0.1 * c )
  Debug StrD(3 + 0.1 * c )
  Debug StrD(4 + 0.1 * c )
  Debug StrD(5 + 0.1 * c )
  Debug StrD(6 + 0.1 * c )
  Debug StrD(7 + 0.1 * c )
  Debug StrD(8 + 0.1 * c )
  Debug StrD(9 + 0.1 * c )
  Debug ""

You are comparing Debug StrD() to Debug (which then uses something like StrF() ). When Debug prints the float, it is printing all the decimals. When you used Debug StrD() you are using it's default precision and it rounds the value off. Try your example with Debug StrD(0.1 * c,18 ) or Debug StrF(0.1 * c) to see the difference.

[Falko]

Yes you have right with Debug.
I've wrote StrD on this, not StrF and not full Decimals.
This would be rounding and is correct.

You can test this and compare Debug and Debug StrD(...) is not the
same as Debug StrF(..)

Code: Select all

For c= 1 To 10
Debug StrD(0.1 * c) + " :Debug StrD"
Debug StrF(0.1 * c) + " :Debug StrF"
Debug "Debug, with no StrF or StrD:"
Debug 0.1*c 
Debug StrD(0.1*c,18)+ " Debug StrD with 18 Decimals" 
Debug StrF(0.1*c,18)+ " Debug StrF with 18 Decimals"
Debug "-------------------------"
Next c

The Floats (StrF) are not exactly accurate as Double (StrD).
The Computer is not a "fast" pocket calculator with high precision

Tested, removed all double declarations, but with the debugger enabled, compiler still crashes with my program (Sorry, I will post no source because 45000 lines of source code!). Without debugger anything works well.

First, Thank you for the update. really rock..

For the good of purebasic here I found small prob on ide.

When I press Alt + F its open a file menu but when I press N to get command New it not work. It goes to all other command in all menu/submenu

other than that its really great. thanks

[Tipperton]

When I press Alt + F its open a file menu but when I press N to get command New it not work. It goes to all other command in all menu/submenu

That's not the only one that doesn't work, pressing Alt-C, then E to build an executable doesn't work either.

I've also noticed that the text of the selected menu option stays black so in a black selection back ground you can't see it.



Personally I liked the menu the way it was in v4.10, it worked.

I have this error when I try to run code created on previous version with debug on.

"This executable was not compiled for this version of the debugger!
Please recompile it to match this debugger version."

And I don't know how to recompile it.

Use the taskmanager and kill the purebasiccompilationX.exe

Sounds like you updated the IDE, but not the debugger library or vice versa.
Try to apply the update again with all PB related programs closed.
