Product of Division

You are given two integers, a and b.

Let x be the integer division and y be the decimal(float) division of a and b.

Return the product of x and y.

Input Format

First Parameter - Integer a

Second Parameter - Integer b

Output Format

Return the decimal product of integer division x and decimal division y of a and b.

Example 1:

Input:
    21
    5
Output:
    16.8
Explanation:
    The int and float value of 21 / 5 is 4 and 4.2 respectively. The product is 16.8

Example 2:

Input:
    11
    4
Output:
    5.5
Explanation:
    The integer and float value of (11 / 4) is 2 and 2.75 respectively. The product is 5.5

Constraints
