I am writing a program to parse a CSV file downloaded from my bank. I have it keep a running balance, but I'm getting a weird total. Apparently, -457.16 + 460.93 = 3.76999999999998. But when 20 is subtracted from that, I get -16.23. There are no weird numbers like that in my input data. All numbers have no more than 2 numbers after the decimal point. Here is my code:

print "<td>$balance</td></tr>\n";
Andrew,
Try using this when you print out the $balance:
printf "%.2f", $balance;
You'll get 3.77.
I was going to use that for output, but I was just curious why it was happening in the first place. I think all the other posts answered that question.
