Hi fellow Monks,
I am new to programming and I have a rather newbie question:
I have a for loop that will calculate some stuff and return a number as a result. This number I have to check each time (until the loop finishes) if it has the highest value (max value). My question is, before I start the loop, how will I declare the variable for the max number? For strings, I know it is $string=''; I can't use $max_numb=0; because I might get negative numbers as well.
The for loop will be something like that:
$max_numb= ???????? --->what should I use here?
for($i=0; $i<=100; $i++)
{
     $number_to_compare=..........;
     if($number_to_compare>$max_numb)
     {
       $max_numb=$number_to_compare;
     }
}
print $max_numb;
