Description

A. First Problemtime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard output

This is the first problem. Not the second, nor the third, but only the very first.

Will you be able to solve it? Well, of course that depends on how hard the problem is and how well you are able to perform at this particular moment in time. But I believe that you can do it! It just might take more or less hypothetical time.

Given the hypothetical difficulty $$$D$$$ of this problem and your hypothetical performance rating $$$P$$$, compute the hypothetical time $$$T$$$ in seconds that it will take you to solve the first problem. You know that $$$T = D / P + 37$$$.

Input

The input to the first problem will consist of a single line containing two space-separated integers: $$$D$$$ and $$$P$$$ where $$$1 \leq P \leq D \leq 10^9$$$.

Output

Print out the value of $$$T$$$, rounded to 3 decimal places.

ExampleInput
615 11
Output
92.909
