Measured Compression Ratio

Problem

Given the original size and the compressed size in bytes, return the compression ratio compressed / original. This equals the ratio of the bit counts, since both sizes scale by the same factor of eight. Return 0.0 when the original size is zero.

Hint

A ratio below 1 means the compressed file is smaller than the original.
