1 \leq B \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the value A \times B as an integer.

Sample Input 1

2 5

Solution in Python (3.8.2) (judge verdict: Accepted)

import math
a,b = map(str,input().split())
a = int(a)

print(math.floor(a*int(float(b)*100+0.1)/100))
