Description
A famous streamer once said: " Abortion Uncle!! Begin abort!!! " The Abortion Uncle is also known as "The Big Hammer Rise". The famous streamer wants to know the exactly time "Big Hammer Rise" kill an enemy. Because he got a double kill, he know exacly two time which denote as a, b.
The famous streamer will give you two number a,b which are represented as float numbers and have two digit after the decimal point.
For example：
If a,b are ranged from 1~99, 1<= a , b < 100;
a,b will be like these forms： 18.00, 99.30, 71.22
You need to calculate ans = a*b, and ans should follow the rule:
if the number of digits after decimal point is less then four digits, then you need to print 0 to make it four digits.
For example: 18.56 -> 18.5600, 18 -> 18.0000, 18.9 -> 18.9000
If you tell him the right answer he will help you kill the ice bird.
( Note: you can use scanf("%d.%d %d.%d", &int, &int, &int, &int). Use %f may cause trouble because the precision of float type. )
( Note: you can use printf("%d.%04d\n", int/10000, int%10000); )
Input
