in reply to Percentage module in Math::?

I agree with most of the others. This is module madness if we need a module to do division.

I will ad this to what the others have said though. Be careful of divide by zero. You may want to do something like this. 

my $percent = ($second_number ? $first_number/$second_number : undef);

And then check $percent for undef.

      If $second_number is a negative zero, shouldn't that give negative undef? (Just kidding.)

      Unless $first_number is also negative. (Being equally serious.)
