No function descriptions were provided. The Lua code may have further information.

local p = {}
local rat = require("Module:Rational")

function p.refrac(frame)
	local n = frame.args["n"]
	local d = frame.args["d"]
	local num, denom = rat.as_pair(rat.new(n, d)) -- hopefully this reduces the numbers
	local whole = frame.args["mixed"] and math.floor(num / denom) or 0
	local ft = (whole ~= 0 and string.format("{{frac|%d|%d|%d}}", whole, num - whole * denom, denom) or string.format("{{frac|%d|%d}}", num, denom))
	return frame:preprocess(ft)
