Thanks for sharing! Unfortunately, bytes representations are wrong.

As you may now, there is a difference between kilobytes (KB) and kibibytes (KiB), megabytes (MB) and mibibytes (MiB) et cetera. 1 KiB = 1024 bytes = 1.024 KB.

Please check out https://en.wikipedia.org/wiki/Binary_prefix and fix your library :)
