Problem detected: Scriptparser is buggy!

Please try it: don't change anything, then compile scripts of any races, overwrite the existing ones and you will see it doesn't work. They won't build freighters/carriers.
Then if you turn the debugger on, you will see that the program can't add any Fighter/cargo bays to the design.
For example:
--------------The result (without changing)----------------
Script_AI_DesignCreation.txt(1470): 1350 * 0 = 0
Script_AI_DesignCreation.txt(1470): 0 / 30 = 0
Script_AI_DesignCreation.txt(1470): 0 + 0 = 0
Script_AI_DesignCreation.txt(1470): Sys_Trunc(0)
Script_AI_DesignCreation.txt(1470): Set num_to_add(10) := 0
------------The original script line------------------------
set num_to_add := Sys_Trunc(((vehicle_tonnage * 0.50) / comp_tonnage) + 0.99)
------------------------------------------------------

If you change the scipt line to this:
set num_to_add := Sys_Trunc(((vehicle_tonnage / 2) / comp_tonnage) + 1)
---------------The result after the changing-----------------
1350 / 2 = 675.00001517686
675.00001517686 / 30 = 22.5000005058953
22.5000005058953 + 1 = 23.4999994594099
Sys_Trunc(23.4999994594099)
Set num_to_add(10) := 23
----------------------------------------------------------
it is just an example. Who knows which things are buggy, too.

I hope now I'm understandable. Sorry, my English is not so good.

No. I spoke about Utilities/Scriptparser/SE5EmpireScripts
These scripts are editable and you can compile them.
When you install the game and start to play everything is ok.
A try: don't change anything and compile for example Default_Main_Script.txt and Default_Setup_Script.txt. you will get two .csf files. Copy them to Empires/Default (overwrite the existing ones) and start a new game. AI (which uses default like neutrals) won't make freighter/carrier designs.

I have an idea. Scriptparser is maybe not buggy but the .txt files . I saw that programmers uses both kind of numbers with 'Sys_Trunc' function, but it seems that it uses real numbers only, because if I change in this function for example '* 0.50' to '/ 2' it will work!
I'm not programmer, I just tried.

No, if you don't change the orginal script files but compile it and overwrite the existing ones, they won't work.

---------
Because of I'm working the translation of this game, I must change them (strings only). So I found this error. First I thought I made a mistake then I tried it with a virgin installation, and I found this error again. Now I'm sure that Sys_Trunc function was used with two kind of numbers was the problem.
If you don't try what I say you won't see.

I dunno, I'm not programmer. I just tried and wrote my observations.
Captain Kwok, please try it for me* and write me what you see. If your version works fine, I have no more idea.

* don't change anything and compile for example Default_Main_Script.txt and Default_Setup_Script.txt. You will get two .csf files. Copy them to Empires/Default (overwrite the existing ones) and start a new game. (Make backup from originals.)
