Compute $A \times B$, truncate its fractional part, and print the result as an integer. ## Constraints * $0 \leq A \leq 10^{15}$ * $0 \leq B < 10$ * $A$ is an integer. * $B$ is a number with two digits after the decimal point. ## Input Input is given from Standard Input in the following format: $A$ $B$ [samples]

Samples

Input #1

198 1.10

Output #1

217

We have $198 \times 1.10 = 217.8$. After truncating the fractional part, we have the answer: $217$.

Input #2

1 0.01

Output #2

Input #3

1000000000000000 9.99

Output #3
