Problem
Every year, Paris welcomes tens of millions of tourists, who bring considerable revenue to the city and its tourist industry. As an employee of the tourism bureau of the city of Paris, you are tasked with computing how much money tourists spent during a particular week. You are given credit card receipts for that week and asked to tally them. Because money is important, you want the exact number, down to the cent.
Input
The input consists of n lines, each containing a decimal number that represents an expense e in euros. Every decimal number is formatted as a non-empty sequence of decimal digits, a point (.) used as the decimal separator, and two decimal digits for the fraction in cents.
Output
The output consists of a single line, whose content is the total expenses, a decimal number in the same format as the input.
Constraints
