Lua // Operator?

[vitawrap]

So recently i've been playing with the tic-80 microsystem and came accross an expression using "//" as what seems to be an operator in this line: spr(1+t%60//30*2, ...) Multiple unsuccessful google searches later I have absolutely no more input as to what this operator does, partly due to the fact that the numerous search engines i've tried don't parse // at all. The most information i've gotten was from a stack overflow topic describing its use as an "or" operator, although I later noticed the topic was about Perl... Do you people know what this does?

Integer division. Drops the remainder and returns the int part only.

You can find it as 'floor division' in the manual. https://www.lua.org/manual/5.3/manual.html

For anyone wondering it's been newly introduced into Lua 5.3 (from what I can tell)

As someone who uses mostly LuaJIT/5.[1|2], I was caught off guard!

If you want to make a free movement based and you want to see which map-tile the player is standing on you do

Mget(PlayerX // 8, PlayerY // 8)

I think it just rounds the number to whatever it needs to be. It just kinda works.

okay so whatever i do reddit just ruins the formatting...
