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:

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