Since nodemcu has not struct.pack support how would you convert an integer to its 16 or 32 bit byte array for binary data transfer?

I have found some lua code but they all depend on math functions that are not supported.

Any Ideas? I am missing something obvious?

Found a good resource on how to handle this. https://svn.nmap.org/nmap/nselib/packet.lua

I doubt the packet.lua able to use on NodeMCU due to limited heap size.
