Fix int overflow that can happen when computing PAR
If the source has large non-reduced PAR values, our computed value
was overflowing an int. Compute it in an int64_t then reduce it.
Also, keep num and den below 65535. Larger values just aren't really
significant and will cause more overflow issues.
