Factorio uses a common encoding method to serialize the version string in binary data that's present in multiple places, such as the map exchange string and save game file format. It consists of four consecutive 2-byte unsigned little-endian values. We'll use version 0.14.21 as an example:

short Factorio's major version number (e.g. 0)
short Factorio's minor version number (e.g. 14)
short Factorio's patch version number (e.g. 21)
short Unknown. Seems to be either 0 or 1.
