Floor a positive float

local result = util.math.floor(4.9)

core.engine.print("info", result) -- 4

Floor a negative float

local result = util.math.floor(-4.2)

core.engine.print("info", result) -- -5

Floor an exact integer returns itself

local result = util.math.floor(3.0)

core.engine.print("info", result) -- 3

Truncate a float to integer

local result = util.math.floor(9.99)

core.engine.print("info", result) -- 9

Compute integer division

local result = util.math.floor(17/5)

core.engine.print("info", result) -- 3

Snap position to grid

local pos_x = 137.6
local grid_size = 32
local snapped = util.math.floor(pos_x/grid_size)*grid_size

core.engine.print("info", snapped) -- 128

Convert seconds to whole minutes

local seconds = 185
local minutes = util.math.floor(seconds/60)

core.engine.print("info", minutes) -- 3
