[raghavendrap]

Hello Friends,

            If 
        $tmp = -524219359 ;
       $tmp1= -532676607;
 
                if($tmp >0 && $tmp1>0){
                     print(Temporary values are greater than Zero);
                else {
                    print(Temporary values are less than zero);
                }
 

May i know what is the result we can get & with some explanation?


Thanks

Hello friends,
I got doubt in doing signed hexadecimal comparision.
Here $tmp & tmp1 are negative decimal values , when i convert that numbers as hexadecimal & comparing with the mentioned below i am getting wrong result.
May i the ultimate solution for signed comparision in perl

 $tmp  = 0xc0211082;
 $tmp1 = 0xc0000082;
 
if($tmp >0 && $tmp1>0){
print("Temporary values are greater than Zero");
}else {
print("Temporary values are less than zero");
}

Correct all syntax errors and retry your code. Its pretty much worthless to ask a question then post bad code, we have no way of knowing if you are getting an error from the bad code or if you are using good code and getting an unusual return value, or what? So please try and always post code that has no syntax errors.
