Hello,

I have found a bug in str2int fuction. I had random problems with my code that converts some data stored in .txt file.
After research I found out that conversion of some numbers gives wrong results. For this moment I found:
-conversion of string "08" gives 0 as result.
-conversion of string "09" gives 0 as result.

Numbers written as string 0X from 0 to 7 after conversion gives expected result (number 0,1,2,3... etc).

As my test I was converting seconds from system time. Conversion performed by str2real gives good results.

Code below:
JAVASCRIPT
using Special.FLibSYS; 
 
	sSeconds = tmFStr(SYS.time(),"%S");
 
	messPut("SecondsString",1,sSeconds);
	messPut("SecondsInt",1,str2int(sSeconds));
	messPut("SecondsReal",1,str2real(sSeconds));




I was using lastest version (r2491).

This is OK but for octal the value "08" and more is wrong!

If you mean that "sSeconds" is strongly decimal then use "base" of the function, like:
messPut("SecondsInt",1,str2int(sSeconds,10));

Then this isn't bug!

Learn, learn and learn better than work, work and work.
