util.mathcompat: Module to ease reuse of math.type()
Mostly to ensure it is available during tests, as util.startup is not
invoked there
if not math.type then
local enum number_subtype
"float" "integer"
end
local function math_type(t:any) : number_subtype
if t is number then
if t % 1 == 0 and t ~= t+1 and t ~= t-1 then
return "integer"
else
return "float"
end
end
end
_G.math.type = math_type
end
