Re: [amibroker] StrMid(NumToStr(1040928),4,3);

Stephane,

Why not just check what NumToStr returns before assuming bug ?

StrMid operates on STRINGs. You can get same results if strings passed are the same
in your case they are NOT. This is so because NumToStr by default returns strings
with thousand separators.

If you investigated a little bit more:

string=NumToStr(1040928); 
mm= StrMid(string,4,3); 
test= StrMid("1040928",4,3); 

you would find that NumToStr(1040928)
gives you sting like this:
"1,040,928.000"

As you can see there are thousands separators there.
Because "1,040,928.000" is different string than "1040928"
characters 4..6 are different too.

If you want string without separators you have to specify this in your 
NumToStr call http://www.amibroker.com/f?numtostr

string=NumToStr(1040928,1,False); 
mm= StrMid(string,4,3); 
test= StrMid("1040928",4,3); 

You can use StrFormat for more control http://www.amibroker.com/f?strformat

string=StrFormat("%.9g",1040928); 
mm= StrMid(string,4,3); 
test= StrMid("1040928",4,3);
