Mighty perl monks, my question might sound amateurt but I have a perls script that runs through a loop 500 times and each time I calculate a value called mutual. From each loop I need the highest value, so I have a few lines of code that do just that . My code is 
push (@holdmutual,$mutual);
            print "vaggos3\n";
}
       
        
        #print " $l,$j,$mutual\n";
      
   }
   
   #end of loop2 for each site2
 
   #print " $l,$j,$mutual\n";
}
      #getting always the highest mutual inforamtion value for each si
+te combination.
        my $highestvalue=0; 
        foreach my $holdmutual(@holdmutual){
        if ($holdmutual>$highestvalue){
            $highestvalue=$holdmutual;
            }print "vaggos4\n";
       }
        print "$highestvalue\n";

Does anyone has a suggestion of a simpler code that does that but it is not as memory intensive as mine? (for example I don't think that I need the array but I am not sure how to get rid of it.) Another thing is that the values I get have a lot of decimals. Is there any way for me to get only the first three decimal values e.g 1.678 instead of what I actually get 1.2345678977885454? Thanks in advance for anyone's help replicant4
