# Batting Average

### Problem Statement

Takahashi is making a computer baseball game.
He will write a program that shows a batter's batting average with a specified number of digits.

There are integers \$A\$ and \$B\$, which satisfy \$1 leq A leq 10\$ and \$0 leq B leq A\$.
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.

For example, if \$A=7\$ and \$B=4\$, then \$dfrac{B}{A} = dfrac{4}{7} = 0.571428dots\$ rounded off to three decimal digits is \$0.571\$. Thus, \$S\$ is `0.571`.

You are given \$A\$ and \$B\$ as the input and asked to print \$S\$.

### Constraints

• \$1 leq A leq 10\$
• \$0 leq B leq A\$
• \$A\$ and \$B\$ are integers.

### Input

The input is given from Standard Input in the following format:

```\$A\$ \$B\$
```

### Output

Print \$S\$ in the format specified in the Problem Statement. Note that answers in different formats will be considered wrong.

```7 4
```

### Sample Output 1

```0.571
```

As explained in the Problem Statement, \$dfrac{B}{A} = dfrac{4}{7} = 0.571428dots\$ rounded off to three decimal digits is \$0.571\$. Thus, \$S\$ is `0.571`.

```7 3
```

### Sample Output 2

```0.429
```

\$dfrac{B}{A} = dfrac{3}{7} = 0.428571dots\$ rounded off to three decimal digits is \$0.429\$. (Note that it got rounded up.)
Thus, \$S\$ is `0.429`.

```2 1
```

### Sample Output 3

```0.500
```

\$dfrac{B}{A} = dfrac{1}{2} = 0.5\$ rounded off to three decimal digits is again \$0.5\$.
Thus, \$S\$ is `0.500`. Note that it must have three decimal places.

```10 10
```

```1.000
```

```1 0
```

### Sample Output 5

```0.000
```
