Float64

Float64 is the default type of a literal containing a decimal point or exponent. Float is an exact alias.

local distance = 12.75
local scale = 6.02e23
local tiny = 2e-3

Float64 supports +, -, *, /, unary -, and all four ordering operators with another Float64.

local whole = Int32(distance) -- 12
local text = String(distance)

Float-to-integer conversion truncates toward zero and traps for NaN, infinity, or an out-of-range result. Primitive string formatting is locale-independent.
