7265: ABC274 —— A - Batting Average
[Creator : ]
Description
There are integers A and B, which satisfy 1≤A≤10 and 00≤B≤A.
Let S be the string obtained as follows.
You are given A and B as the input and asked to print S.
Let S be the string obtained as follows.
- Round off $\dfrac{B}{A}$ to three decimal digits, then write the integer part (1 digit), . (the decimal point), and the decimal part (3 digits) in this order, with trailing zeros.
You are given A and B as the input and asked to print S.
Input
The input is given from Standard Input in the following format:
$A\ B$
$A\ B$
Output
Print S in the format specified in the Problem Statement.
Note that answers in different formats will be considered wrong.
Note that answers in different formats will be considered wrong.
Constraints
1≤A≤10
0≤B≤A
A and B are integers.
0≤B≤A
A and B are integers.
Sample 1 Input
7 4
Sample 1 Output
0.571
As explained in the Problem Statement, $\dfrac{B}{A} = \dfrac{4}{7} = 0.571428\dots$ rounded off to three decimal digits is 0.571. Thus, S is 0.571.
Sample 2 Input
7 3
Sample 2 Output
0.429
$\dfrac{B}{A} = \dfrac{3}{7}=0.428571…$ rounded off to three decimal digits is 0.429. (Note that it got rounded up.)
Thus, S is 0.429.
Thus, S is 0.429.
Sample 3 Input
2 1
Sample 3 Output
0.500
10 10
1.000
Sample 4 Input
